Answer 1

Find the value of x. Diagram not to scale.

Answer 2

To find x we need to do two steps:

Use the strait line rule to find 'y', then use the sum of interior angles to find x.

Answer 3

Okay?

Answer 4

in a straight line, the two angles equal 180 degrees...so if 1 angle is 116, then angle y is 180 - 116 = 64 degrees.

to find the sum of the interior angles of a polygon, use this formula
S = (x - 2)(180) ---- x being the number of sides
S = (4 - 2)(180)
S = 2(180)
S = 360

so our interior angles have to equal 360
so we have : 360 - (125 + 72 + 64)
360 - 261 = 99

so y = 64 degrees and x = 99 degrees
