Hello from MrBillDoesMath!
Answer:
45 (all three: 45, 45, 90)
Discussion:
Let "x" be the base angle in the isosceles triangle. As base angles are equal in an isosceles triangle and a triangle contains 180 degrees:
x + x + 90 = 180 =>
2x + 90 = 180 => subtract 90 from both sides
2x = 180 -90 =>
2x = 90 => divide both sides by 2
x = 45
Thank you,
MrB
