Question

a) two- third(2/3) of a straight angle____.

b) three-fifth(3/5) of a right angle____.

c) 2 times 60 degrees_____

d) 4 times 90 degrees____.

e) one-fifth of a complete angle_____.​

Answer 1

Answer:

1. 2/3× 180= 120

2. 3/5 × 90= 18× 3= 54

3. 2×60= 120

4. 4× 90 =360

5. 1/5 × 360 = 72.

Answer 2

$\huge\underline{\tt Answer}$

$\frac{2}{3}$ of a straight angle = $\frac{2}{3}$ × 180° = 120°

$\frac{3}{5}$ of a right angle = $\frac{3}{5}$ × 90° = 54°

2 times 60° degrees = 2 × 60° = 120°

4 times 90° degrees = 4 × 90° = 360°

$\frac{1}{5}$ of a complete angle = $\frac{1}{5}$ × 360° = 72°
