Question

the angle of triangle are (x + 10) (2x-30°) find the value of "X"​

Answer 1

Answer:

The x+10,2x−30,x are angles of triangle 

By angle sum property 

Sum of all angles is 180

x + 10 + 2x − 30 + x = 180

4x − 20 = 180

4x = 180 + 20

4x = 200

x = 200/4

x = 50

Answer 2

Answer:

We know that the sum of the angles of a triangle is 180 degree.

(x + 10) + (2x - 30) + x = 180

x + 10 + 2x - 30 + x = 180

4x - 20 = 180

4x = 200

x = 200/4

x = 50
