How do you find the interior angle of a triangle given the external angle of 125°
Answer:
<x = 55 degrees
<y = 55 degrees
<z = 70 degrees
Step-by-step explanation:
The 125 degree angle and x are supplementary since they form a straight line, which means that their degrees add up to 180. To find x, the interior angle, we must subtract 125 from 180.
180 - 125 = 55
Angle x is 55 degrees. Since the sides opposite x and y are marked with lines, they are congruent, and since the sides are congruent, the angles must be, too. So, y is also 55 degrees.
Finally, the angles in any triangle add up to 180 degrees. To find z, we must subtract the values of x and y from 180.
180 - 55 - 55 = 70, so z is 70 degrees.
Brainliest, please :)
❄Hi there,
the external angle & the interior angle form a linear pair, which means, if you add these angles together, you'll arrive at 180°.
Using this knowledge let's set up an equation and find x:
[tex]\triangleright \ \sf{125+x=180}[/tex]. We let x be the desired angle.
[tex]\triangleright \ \sf{x=180-125=55}[/tex]
So the interior angle is [tex]\angle\sf{55}\textdegree[/tex].

Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that to fit in an existing frame, the length, x, of a piece of glass must be longer than 12 cm but not longer than 12.2 cm.
It means that the length has to be strictly greater than 12 cm but less than or equal to 12.2 cm. In other words, length of frame must be longer than 12 cm means that x>12, while ength of frame not longer than 12.2 cm means x≤12.2

A family is having a pool built in their backyard. If their yard is rectangular and measures 10x by 10x and the pool is circular with a radius of 2x how much of the yard will be left over after the pool is built
Answer:
[tex]100x^2-4\pi x^2[/tex]
Also can be said as:
[tex]4x^2(25-\pi )[/tex]
Step-by-step explanation:
The scenario:The question is asking you, "how much is left over."
In this scenario, you're going to have to subtract the area of the pool (P) from the total area of the backyard (B), which will leave you with the remaining area of the backyard (x).
This means your equation to solve this question is:
[tex]x=B-P[/tex]
Step 1:The value of B is the area of the backyard.
We are told that the backyard is a rectangular shape. So, we can use the formula of finding the area of a rectangle.
The formula is [tex]B=L*W[/tex], where L is the length and W is the width.
Both the length and width are 10x, so we must plug that into this equation.
We end up getting:
[tex]B=10x*10x[/tex]
Which can be simplified to:
[tex]B=100x^2[/tex]
Step 2:The value of P is the area of the pool.
The pool is a circular shape. So, to get the area of it, we must use the formula of finding the area of a circle.
The formula is [tex]P=\pi r^2[/tex], where r is the radius.
Plugging in the radius of 2x, we get:
[tex]P=\pi (2x)^2[/tex]
By solving this out, we end up with:
[tex]P=4\pi x^2[/tex]
Step 3:From the scenario, we have the equation:
[tex]x=B-P[/tex]
And from steps 1 and 2, we have the values:
[tex]B=100x^2[/tex] and [tex]P=4\pi x^2[/tex]
Now we just plug those values in to get:
[tex]x=100x^2-4\pi x^2[/tex]
And finally, the amount of the backyard remaining is:
[tex]100x^2-4\pi x^2[/tex]
Different format:This answer may be simplified to:
[tex]4x^2(25-\pi )[/tex]

Using proportions, it is found that the federal tax rate is of 10%.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The tax rate is the proportion that $17.50 is of $175, hence:

Also, we can see that the y-intercept is y = 4, that means that the constant term of the parabola is 4.

what is the value of x
find the value of f
Answer:
x = 20°
f = 40°
Step-by-step explanation:
4x + 5x = 180°
because a straight line is 180°
so 9x = 180°
1x = 180 ÷ 9
1x = 20
all angles in a triangle add together is 180°
so 7x + f = 180°
1x = 20
7x = 20 × 7
7x = 140°
f = 180° - 140 °
f = 40°
Answer:
x = 20 , f = 40
Step-by-step explanation:
4x and 5x are a linear pair and sum to 180° , then
4x + 5x = 180
9x = 180 ( divide both sides by 9 )
x = 20
then
5x = 5 × 20 = 100° and 3x = 3 × 20 = 60°
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
5x is an exterior angle of the triangle , then
f + 3x = 5x , that is
f + 60 = 100 ( subtract 60 from both sides )
f = 40

What are trigonometric functions?It should be noted that the trigonometric functions are the real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
There are six functions of an angle. They are sine (sin), cosine (cos), tangent (tan), cotangent, secant, and cosecant (csc).
It should be noted that all the y-coordinates of a reciprocal function will be the reciprocals of the y-coordinates of the original function. Then, the graph of a reciprocal function has a vertical asymptote at each zero of the original function. For example, y=arcsinx reflects against y=sinx.
