Jed used a protractor to draw an angle measuring 72°. He asked Mark to draw an angle that would be complementary to his angle. What should the measure of Mark's angle be? A.
144°
B.
18°
C.
108°
D.
162°

B

Step-by-step explanation:

Complementary angles are 2 angles that add up to 90 degrees.

If the first angle is 72 degrees, then subtract 90 - 72 to get the measure of the second angle.

90 - 72 = 18

= 18 degrees

correct answer:

a + bi

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
