Question

of a triangle
Qis (2x + 20)
R is (x + 70). P is (2x+10)
find the unknown angle​

Answer 1

Step-by-step explanation:

Here unknown angle is x

So, according to properties of triangle sum of all angles= 180°

Given, angles are 2x+20, x+70, 2x +10

2x+20+x+70+2x10=180

5x+100=180

5x=180-100

5x=80

x=16

Therefore the unknown angle x is 16
