The sum of all the internal angle is [tex]$180^{\circ}$[/tex].
What is Internal angles?The internal angle formed by a closed polygon's sides inside of itself. A shape's interior can contain angles. The closed, side-and-vertex-containing shapes are known as polygons. All of the internal angles of a regular polygon are equal. For instance, the inner angles of a square are all exactly 90 degrees, or the right angle. Triangles always have three inner angles that add up to 180 degrees. Because the other two angles (180°+0°+0°) would not be present, a triangle cannot have an individual angle of 180°.The sum of all the internal angle is [tex]$180^{\circ}$[/tex].

A chemist is using 329 milliliters of a solution of acid and water. If 13.4% of the solution is acid, how many milliliters of acid are there? Round your answer to
the nearest tenth.
I milliliters
х
5
?
Answer:
44.1mm
Step-by-step explanation:
Given
Total solution of acis nad water = 329mm
Percentage that is acid = 13.4%
Amount that is acid = 13.4% of 329
Amount that is acid = = 13.4/100 * 329
Amount that is acid = 13.4*3.29
Amount that is acid = 44.086
Hence the amount of acids there is 44.1mm
Tom is playing at the opposite corner of the playing field to his friend . If the playing field is 180m wide and Tom is 300m away from his friend, how long is the playing field
Answer:
240 m
Step-by-step explanation:
we can picture this as a right triangle
(180)^2 + (l)^2 = (300)^2
300 would be the diagonal of the triangle since it is at the opposite corner
180 would be the height/leg of the triangle

How many points does a student need to score 70% on a 80 point test?
Answer: 56
Step-by-step explanation:
70÷100×80=56
Answer:
56
Step-by-step explanation:
Another way to write this question is "What percent of 80 is 70%."
So we would write a percent proportion:
x/80=70/100
To find x, we will do (80*70)/100 which is 5600/100 which is 56.
You could also use benchmark fractions:
10% of 80 is 8
10% * 7 = 70% so 8 * 7 also equals 70%
8 * 7 = 56

The area of a triangle A is given as A =1/2 bh, where b is the base an h = height. (a) find h if A =30 and b=10
Answer:
h = 6
Step-by-step explanation:
Substitute the given to its corresponding places.
30 = [tex]\frac{1(10)h}{2}[/tex]
30 = 10h/2
Multiply both sides by two to remove the denominator.
2 [30 = 10h/2] 2
60 = 10h
Divide both sides by 10 to isolate h.
h = 6
To check, substitute everything to the original equation:
A = [tex]\frac{1(10)(6)}{2}[/tex]
A = 30 !

Last Sunday 1,575 people visited the amusement park. 56% of the visitors were adults, 16% were teenagers, and 28% were children ages 12 and under. Find the number of adults, teenagers, and children that visited the part.
Answer:
Adults
= Percentage of adults * Total number of people who visited
= 56% * 1,575
= 882 adults
Teenagers
= Percentage of teenagers * Total number of people who visited
= 16% * 1,575
= 252 teenagers
Children
= 28% * 1,575
= 441 children
