Question

two angles of triangle are 45 degree and 55 degree find the measure of third angle​

Answer 1

Step-by-step explanation:

We know that angle sum property

sum of sides = 180

45+55+x =180. ( let third side be x)

x+100 = 180

x= 180-100

x = 80

Answer 2

Answer:

By A.S.P.

45°+55°+X°=180°

100°+X=180°

X=180°-100°

X=80°

So, the third angle is 80°.
