Question

answer this question with step by step explanation class 7 And who ever will give me the correct answer I will mark him or her as brainlist​

Answer 1

∠5 and ∠1 are corresponding angle

hence m∠1 and m∠5 are same

so 2x+40° = 3x+20°

or 3x-2x = 40°-20°

or x = 20°

so m∠5 = 40°+40°= 80°

Answer 2

Answer:

80°

Step-by-step explanation:

∠5 and ∠1 are corresponding angle

hence m∠1 and m∠5 are same

so 2x+40° = 3x+20°

or 3x-2x = 40°-20°

or x = 20°

so m∠5 = 40°+40°= 80°
