Answer:


x=45

Explanation:

→a+b+c=180

→Angle a is given to be 90 degrees

→ Also the other to angles are the same length so the same angle


90+2x=180

Step 1: Subtract 90 from both sides.


2x+90-90=180-90


2x=90

Step 3: Divide both sides by 2.


(2x)/(2) =(90)/(2)


x=45

x=45

Answer:

x=45 degrees

Explanation:

You can see based off of the markings on the 2 sides, that it is an isosceles triangle, so that means the 2 base angles are equal.

so 2x+90=180 degrees

so 2x=90 degrees

x=45
