Question

Two geometry questions

Answer 1

In prblem 3. you have a quadrilateral.

The sum of the measures of the interior angles of a polygon is (n - 2)180, where n = number of sides. For a quadrilateral, n = 4, so the sum of the measure of the angles is (4 - 2)180 = (2)180 = 360

The angle that measures y is supplementary to the angle that measures 111, so
111 + y = 180
y = 69

The sum of all angles is 360 so:
69 + 66 + 121 + x = 360
x = 104

Answer 2

How about you try solving problem 4, and if you have questions we'll discuss it.
