Question

The angles in a triangle are in the ratio of 1: 2: 5. The largest angle is: select one:
a. 22.5 degrees
b. None of these
c. 112.5 degrees
d. 45 degrees

Answer 1

Answer:

Step-by-step explanation:

Take each side as 'x'.

So x + 2x + 7x= 180°.

X = 180/8

= 22.5

Since the largest side is 5x,

5x= 22.5×5= 112.5

Therefore, the answer is (c) 112.5°
