Help please - corresponding parts of congruent triangles

79

Step-by-step explanation:

Solve for X first

(4x-10)=(2x+6)

4x−10−2x=6

2x−10=6

2x=6+10

2x=16

x= 16/2

x=8

Because x is 8, you can now solve 4x-10 and 2x+6.

4x-10

4(8)-10

32-10

22

2(8)+6

16+6

22

Both B and D are 22.

180-22

158

158/2

79

79+79+22=180

A, C, F, and E are all 79.

This means A=79

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
