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
