# If ABC is a right triangle and angle A=45°, what degrees are B and C?

As the sum of internal angles of a triangle is

If angle A is

Angle A + Angle B + Angle C=180 degree

45+45+90=180

180=180

Hope it helps!

If (\angle A) in triangle ABC is (45^\circ) and ABC is a right triangle, then (\angle B) and (\angle C) are complementary angles because the sum of all angles in a triangle is (180^\circ). Since (\angle A) is (45^\circ) and it's a right triangle, either (\angle B) or (\angle C) must be (90^\circ). Therefore, (\angle B) and (\angle C) are (45^\circ) and (90^\circ) respectively, making (\angle B = 45^\circ) and (\angle C = 90^\circ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
