Question

find the value of x

please help​

Answer 1

Answer:

Step-by-step explanation:

let us name the triangle ABC

angle A=x

B=180-125(linear pair)

B=55

C=180-130(linear pair)

C=50

angle A+B+C=180(A.S.P)

A=180-(50+55)

A=75

X=75

Answer 2

construction:-draw the line parallel to base.

angle formed by constructed line and side of triangle=130°..........[alternate interior angles]

x+130°=180°........[linear pair]

x=180-130

x=50°
