Question

help me in this question​


step by step explanation

Answer 1

Answer:

x/2+3x+x=180° ( because angle formed a linear pair) eq--1

x/2+4x=180°

x+8x/2=180°

9x/2=180°

9x=180×2

x=360/9

x=40cm

So,L1=40/2

L1=20°

L2=3×40

L2=120°

L3=40°

Step-by-step explanation:

For check we put value of x in place of eq--1

20+120+40=180°

180°=180°

Hence proved that our answer is correct.
