Question

The sum of two angles is 200° and their difference is 80°. Find the angles.​

Answer 1

Step-by-step explanation:

ATQ

x+y=200°----(1)

x-y=80°

x=80°+y--(2)

Put the value of x in eq 1

80°+y+y=200°

2y=200°-80°

2y=120°

y=120°/2

y=60°

Put the value of y in equation 2

=>x=80°+60°

x=140°

Answer 2

Answer:

a+b =200°

a-b =80°

by adding them both

(a+b)+(a-b)

2a=200°+80°

2a=280°

a=280/2=140°

b=200-140=60°

Hence proVed 140-60= 80°

a=140°

b=60°
