Question

find the measure of the third angle of a triangle
a) (?)A =90. ,B=10.​

Answer 1

Answer:

80°

Step-by-step explanation:

Sum of angles in a triangle = 180°

So,third angle={180°-[90°+10°]}

=80°

Answer 2

Answer:

80 degrees

Step-by-step explanation:

Sum of angles in a triangle = 180

A + B + C = 180

90 + 10 + C = 180

C = 180 - 100

C = 80 Degrees
