Question

One of the acute angles of a right angle is 50.what is the measure of all three angles in a triangle

Answer 1

As we know that IN any triangle A+B+C =180° . now as triangle is right so one angle let A=90 and other angle let B=50 so we have to find C put values of A and B

90 +50+C =180

120 +C = 180

C= 180–120

C=60

Answer 2

it is always 180 and bonus for you the formulae to find the measure of all angles is (n-2)180 where n=number of sides

Example in rectangle no. of side is 4 so n=4

(4-2)180

(2)180

=360
