Answer: x = 13; y = 13√2
because this is a right triangle, we have:
tan 45° = x/13
⇔ x/13 = 1
=> x = 13
we also have:
cos 45° = 13/y
⇔ 13/y = 1/√2
⇔ y = 13√2

Answer:
Step-by-step explanation:
Given: pentagon (5 sided polygon), two interior angles = each, other three interior angles are congruent.
Sum of angles in a polygon = (n - 2) ×
where n is the number of sides of the polygon.
For a pentagon, n = 5, so that;
Sum of angles in a pentagon = (5 - 2) ×
= 3 ×
=
Sum of angles in a pentagon is .
Since two interior angles are right angle, the measure of one of its three congruent interior angles can be determined by;
- (2 × ) = -
=
So that;
the measure of the interior angle =
=
The measure of one of its three congruent interior angles is .
