Question

A triangle whose two angles measure 40 degrees and 100 degrees is *

Answer 1

Answer:

a+b+c = 180

a=40

b= 100

c= x

100 + 40+ c = 180

c=180 -140

c=40

Answer 2

Measure of two angles= 40 and 100
Let third angle = x
We know measure of all the angles of a triangle= 180
100+40+x= 180
140+x = 180
x= 180-140
x=40
Third angle=40
