Find the Angle
xo
65o
The diagram below shows two equal sized squares. Calculate the size of angle x. Show your working clearly and explain your reasoning.
Apex angle of the triangle = 180o – 130o = 50o (Angle sum triangle)The triangle has two equal sides and so is isosceles with base angles equal.
The three angles opposite angle x sum to 90o + 50o + 90o = 230o
Angle x = 360o - 230o = 130o (Angles at a point)
