Question

If the measure of one angle of a triangle is 40 degrees
and difference of measures of other two

angles is 20 degrees then find other two angles.​

Answer 1

Answer:

60° & 80°

Step-by-step explanation:

180-40=140°

x+y=140 -----1

x-y=20 -------2

on solving 1 & 2

2x=160 therefore x=80°

x+y=140

80+y=140

y=60°

Answer 2

Measure of one angle equals 40

Let the other two angles be x and y

x + y + 40 = 180

x + y = 140---1

x - y = 20 (as per problem). -----2

Adding 1 and 2

2x = 160

x = 80

y =140 - 80

y = 60
