Question

Find the supplement of four third of an right angle triangle

Answer 1

Right angle= 90°

First we need to find what is the 4/3 of 90°.

There are two ways-

1).
⇒ 4/3×90
⇒ 120°

2).
⇒ 90÷3 →30 (1/3 of 90)
⇒ ∴, 30×4 → 120°

Now, to find the supplement,

⇒ 180-120
⇒60°

∴, the supplement of 4/3 of 90° is 60°.
