Question

how many degrees are there in 2/3 of a right angle

Answer 1

----------------------------------------

Here is the solution:

----------------------------------------

Right angle = 90°

Find 2/3 of a right angle:

2/3 x 90 = 60°

Answer: 2/3 of a right angle is 60°

Answer 2

$What \: is \: a \: right \: angle?$


$it \: is \: an \: angle \: of \: measure \: 90°$

$what \: is \: \frac{2}{3} \: of \: a \: right \: angle \:$
$\frac{2}{3} \: of \: a \: right \: angle \: = \: \frac{2}{3} of \: 90° \: (of \: here \: denotes \: multiplication) \\ = \frac{2}{3} \times 90° \\ = \frac{180}{3} \\ = 60°.$
Therefore 2/3 of a right angle is 60° and it's complement will be:

(3/3[whole]-3/3)*90°.

= 1/3*90.
= 90/3.
= 30°.
