Question

Plz find the value of x and y

Answer 1

Answer:

x=50

y=80

Explanation:

Since the exterior angle equals 130°, and we know that the angle of a straight line is 180° then the angle (ACB) (lets call it Z) equals 180-130 = 50.

and since side AC = AB, then angle Z = X, which means that X is 50

And we know that the sum of all angles in a triangle equals 180 (Y+X+Z=180) then:

Y(what we want) = 180-(X+Z) so by substituting in X and Z that we just got.

180-(50+50) = 80
