Question

7. Write the measures of the supplementary angles of the following angles:
(b) 120°
(C) 130°
(d) 28°
(e) 90°
(a) 60°​

Answer 1

Answer:

A . 60

B . 50

C . 152

D .90

E .120

Step-by-step explanation:

The finding of this method is

Example :

180 - 120.=60

180 - 130 = 50

180 - 28 =152

180 - 90 =90

180 - 60 =120

Answer 2

Answer:

Supplementary angle measures = 180°

a) 120°

ans: 180° - 120°

= 70°

b) 130°

ans: 180° - 130°

= 50°

c) 28°

ans: 180° - 28°

= 152°

d) 90°

ans: 180° - 90°

= 90°

e) 60°

ans: 180° - 60°

= 120°
