Question

find the value of a and b​

Answer 1

x = 18 and Angle A = 166°

$angle \: a \: = angle \: b \: \: \: \: (corresponding \: angles) \\ 7x + 40 = 3x + 112 \\ 7x - 3x = 112 - 40 \\ 4x = 72 \\ x = \frac{72}{4} \\ x = 18 \\ angle \: a \: = 7x + 40 \\ = 7 \times 18 + 40 \\ = 166$

Answer 2

Answer:

A=166°, B=166°

Step-by-step explanation:

A=B______(corresponding angles)

7x+40=3x+112

7x-3x=112-40

4x=72

x=72/4

x=18

A=7x+40

= 7(18)+40

= 126+40

=166°

B=3x+112

=3(18)+112

=54+112

=166°
