Question

find the sum of angle of triangle is 180 the angle of a triangle are (x-40) , (x-20) , (x/2-10). find the value of x and then the angle of triangle.

Answer 1

Hello Dear!!!!

Here's your answer...

Given,

Angles are (x-40) , (x-20) , (x/2-10)

Sum of these angles is 180

x-40+x-20+x/2-10 = 180

2x-70+x/2 = 180

2x+x/2 = 180+70

4x/2 + x/2 = 250

5x/2 = 250

5x = 500

x=100

angles are 

x-40 = 100-40 = 60

x-20 = 100-20 = 80

x/2 - 10 = 50-10 = 40


angles are 60,80,40
