The angle measure BAC is the sum of angles BAD and CAD.
What are Angles?Angles are the figure formed by the intersection of two lines or rays by sharing a common point. This point is called the vertex of the angle.
Given a triangle ABC.
A line is drawn inside the triangle from vertex A to the opposite side BC.
Given that AD = BD = CD.
That is the line AD bisects the line BC.
So here we have two smaller triangles ABD and ACD.
Two corresponding sides of both the triangles are equal.
Then the third side is also equal.
AB = AC
And we get angle A is bisected.
By the angle bisector theorem,
Measure of angle BAC = Measure of angle BAD + Measure of angle CAD
Hence, Measure of angle BAC = Measure of angle BAD + Measure of angle CAD

Answer:
g(g(x)=25x
Step-by-step explanation:
g(g(x) is a composition function. Think of g(x) as input. That means whatever g(x) equal that will be inside of the function g(x)
g(x) equal 5x so 5x will be the equal value going into the function g(x)

An arithmetic sequence has second term 28 and the fifth term 52. (3 marks) a. Find u1 and d. b. Find u10
Answer: See explanation
Step-by-step explanation:
Second term = a + d = 28 ....... i
Fifth term = a + 4d = 52 ......... ii
Subtract equation I from ii
3d = 24
d = 24/3 = 8
d = common difference = 8
Since a + d = 28
a + 8 = 28
a = 28 - 8 = 20
First term = a = 20
u10 = a + (n-1)d
= a + (10-1)8
= 20 + (9 × 8)
= 20 + 72
= 92

Ted and Mary ordered meals costing a total of $30, including tax. They left an 18% tip. How much did they spend in all?
A $48.00
B $39.00
C $36.40
D $35.40
Answer:
D $35.40
Step-by-step explanation:
We need to find 18% of $30 and then add it to the $30 total.
To find a percent of a number, change the percent to a decimal by moving the decimal point two places to the left. Then multiply it by the number.
18% of $30 =
= 18% * $30
= 0.18 * $30
= $5.40
The tip was $5.40. Now we add the tip to the total.
$30 + $5.40 = $35.40
Answer: D $35.40
