Question

8. Write the complement of each of the following angles :
(1) 46°
(2) (x + 12)°
(3) 90°
(4) 34° 27'
(5) 3/4of a right angle

(6)42° 36' 25"​

Answer 1

I) complement = 90

therefore 90-46=44

ii)X+12= X=90-12

X=78

iii) 90-90

=0

iv) is that 34 if 34 subtract it from 90

v) 3/4 of 90

= 3/4×90-90

= -22.5

Answer 2

Answer:

1) 44°

2)(78 - x)°

3)0°

4) -55.55

5) 1/4 of a right angle = 22.5°

6)47.393°

Explanation:

complementary angles means sum of angles must be 90°

60' = 1°

3600'' = 1°
