Question

I a ∆ABC,if angle A=55°and angle B=75°,then find the angles​

Answer 1

Answer:

50 degree

Step-by-step explanation:

sum of all angle in triangle is 180 degree so 55+75=130 and 130-180=50

Answer 2

Answer:

The third angle is 50°

Step-by-step explanation:

As we know the sum of 3 angles of a triangle is 180°,

so in the given question we have to find the angle C

and angle A and angle B are given:

Let angle C : x

angle A: 55°

angle B: 75°

A+B+C= 180°

55 +75+ x= 180°

130+ x = 180

x= 180-130

x = 50°

Hope this help you :)
