4. don designed a triangular-shaped garden. use the diagram to answer each question.

a. what kind of triangle is formed by the sides of the garden?
b. what is the measure of angle x?

This is a 45-45-90 triangle or a right triangle created by the sides.

Because of this being a right triangle and 45 degrees being given already for one angle you would add 90 and 45 which will give you 135. You would subtract 135 from 180 because all the angles of a triangle add up to 180°. 180-135=45. X=45°
