Question

In a right angled triangle, an angle measure 350

, then find the measure of the third angle.

A) 45 degree

b) 55 degree

c) 165 degree

d) 35 degree​

Answer 1

Answer:

let triangle ABC be the right-angled such that angle C = 35

o

.

Now,

∠A+∠B+∠C=180

o

⇒∠A=180

o

−90

o

−35

o

⇒∠A=55

o

Therefore, third angle of triangle is 55

o
