Question

Angle A and Angle B of a triangle are 35 and 55 degrees .The measure of third angle should be​

Answer 1

Sum of all the angles of a triangle should sum upto 180 degrees.

Therefore ,

Angle A + Angle B + Angle C = 180

let Angle C be x .

=> 35 + 55 + x = 180

=> x = 180 - 90

=> x = 90 .

Therefore third angle should measure 90 degree.

Hope this helps.

Have a nice day !

Answer 2

Answer:

Sum of all the angles of a triangle should sum upto 180 degrees.

Therefore ,

Angle A + Angle B + Angle C = 180

let Angle C be x .

=> 35 + 55 + x = 180

=> x = 180 - 90

=> x = 90 .

Therefore third angle should measure 90 degree.
