Question

Need help on problem seven thank you

Answer 1

Given: <A = <D

<A = 4x - 20 and <D = x + 19

so

4x - 20 = x + 19

3x = 39

x = 13

<A = 4(13) -20 = 52 - 20 = 32

Answer

<A = 32°

Answer 2

(3)

we are given

angle(A)=angle(D)

A=4x-20

D=x+19

now, we can set it equal

`4x-20=x+19`

now, we can solve for x

`4x-x=20+19`

`3x=39`

`x=13`

now, we can find angle A

`A=4*13-20`

`A=32`..............Answer
