Question

Solve for the angles x and y

I really really need help this is for a big test

Answer 1

x=127°

y=53°

Explanation:

to understand this

you need to know about:

• polygon

tips and formulas:

• sum of any polygon interior angles:(n-2)×180°
• the given shape is a heptagon
• a line contains 180°

let's solve

step-1: find the sum of the polygon interior angles

=(7-2)×180°

=5×180°

=900°

step-2: find x

according to the question

113+112+123+168+99+148+x=900

=>773+x=900

=>x=900-773

therefore

x=127

according to the question

127+y=180

=>y=180-127

therefore

y=53
