Answer:

x=45

Step-by-step explanation:

The angles of a triangle <em>always </em>adds up to a total of 180 degrees. Since we are given two angles, we can solve this.

Hi! :)

So a right triangle is a triangle that contains a ninety degree angle, it's not classified by side length. A scalene triangle is a triangle in which all three sides are different lengths. An isosceles triangle has two sides that are the same length. Either a scalene or an isosceles triangle could contain a right angle, so your answer is yes. 

Hope this helps!
