Question

if a triangle has one angle equal to 55 degree and other and two angles differ by 35 degree, then find the other two angles

Answer 1

Let the unknown angle = x

therefore second unknown angle = x-35

known angle = 55

Using Angle sum property -

x+x-35+55= 180

2x+20 = 180

x = 180-20/2

x = 80

therefore second angle = 80 - 35

= 45
