Question

(b) A triangle has one acute angle as the complement of the other. Find the third angle.
if you don't know then don't answer​

Answer 1

Answer: 90°

Step-by-step explanation:

We know that the sum of two complementary angles = 90°

Now,

let the two complementary angles be x and y and the third angle be zero.

therefore, x + y = 90°...........(i)

According to angle sum property of a triangle,

the sum of all angles of a triangle = 180°

therefore,

x+y+z = 180

or 90 + z = 180 [putting the value of x+y from

equation (i) ]

or z = 180-90

or z = 90

Therefore the third angle is 90°.
