Question

3. Find the measure of x. a 18° b. 54° C 126 d. 45

Answer 1

Answer:

18 degrees

Step-by-step explanation:

The triangle is an iscoceles right triangle.

The angles in a triangle add up to 180.

90+2y (iscoceles) =180

2y=90

y=45

So the angles of the right triangle are 45. However, you have to take away 27 because you are solving for only a part of 45. 45-27=18

Answer 2

Simple 18 degrees, when you find the measure of x and find the Isosceles triangle
