Question

find x,y value describe​

Answer 1

Step-by-step explanation:

Here one side angle of triangle is given = 70°

First we will find y

y = 180 - 120

y = 60°

And as we all know that the sum of triangle angle is 180.

=> a + b + c = 180°

=> 70 + 60 + y = 180

=> 130 + y = 180

=> y = 180 - 130

=> y = 50°

Hence, the angles are 70°, 60° & 50°
