Answer:
The number of degrees in an acute angle of an isosceles right triangle is 45 degrees.
Step-by-step explanation:
An isosceles right triangle has two congruent base angles, and one 90 degree angle. Since a triangle's degrees will always equal 180, we would make an equation like so:
180 (total degrees) = 90 (right angle) + 2x (base angles)
90 = 2x
45= x
