Question

answer plz............

Answer 1

Answer:

x = 10°

Step-by-step explanation:

angle A + angle B = 180°  (co-interior angles)

5x + 34° + 2x + 76° = 180°

7x + 110° = 180°

7x = 180° - 110°

7x = 70°

x = 10°

Answer 2

Step-by-step explanation:

by observation of diagram

$∠A+ ∠B= 180 \\ (5x + 34 )\: \: + (2x + 76) = 180 \\ 7x + 110 = 180 \\ 7x = 180 - 110 \\ 7x = 70 \\ x = 10$

Now angle ∠A = 5x + 34

= 5×10 +34

= 84°
