Answer:

Step-by-step explanation:

Both bottom angles are equal

So x+x+48=180

Subtract 48 from both sides

So 2x=132

Divide both sides by 2

x=66

You can tell that this triangle is an isosceles triangle as both sides are the same length. In an isosceles triangle, the bottom two angles are always equal. The angles in a triangle always add to 180 degrees. You are given the fact that the top angle is 48 degrees. If you do 180 - 48, that will give you 132 degrees, which is the sum of the bottom two angles. If you divide that by 2, you will get 66 degrees, which is one of the angles.

Therefore, x = 66 degrees.

A quadrilateral with only 2 right angles could be a trapezoid so Balavan is wrong. Denna is right because if 3 angles are right angles the the fourth angle must also be a right angle and has to be a square or rectangle.
