triangle ABC with rigth at C
Chat with our AI personalities
'a' and 'b' must both be acute, complementary angles.
It depends on what your measuring and the measure of the other given angles. "X" is also known as the missing angle. ex. In triangle ABC, the measure of angle A is 40 and the measure of angle B is 80 find the missing angle. answer- Angle C would be 60 because a triangle's angles add up to 180 degrees.
As we know that all angles of a triangle = 180 degrees So, Angle A + Angle B + Angle C = 180 degrees So, 100 + 17 + x = 180 Angle C = 180 - 117 Angle C=63 degrees
A = 18.1 degrees B = 54.3 degrees C = 107.6 degrees
