Question

6. The measure of an angle which is equal to its complement is
(a) 60° (6) 30° c ) 45 (d) 150​

Answer 1

Answer:

45

Step-by-step explanation:

let angle be x

x+x=90

2x=90

x=90÷2

x=45

Answer 2

Step-by-step explanation:

a] x= 60(90-x)

   x=5400-60x

61x=5400

   x=5400/61

b] x=30(90-x)

   x=2700-30x

31x=2700

   x=2700/31

c] x=45(90-x)

   x=4050-45x

46x=4050

   x=4050/46

   x=2025/23

d] x=150(90-x)

   x=13500-150x

151x=13500

     x=13500/151
