b.30°
c.60°

with explanation​

Answer 1

Answer:

a. 45

Explanation:

it is a right answer

Answer 2

Answer:

a. answer=7

b. answer=11

c. answer=5

Explanation:

By the formula:-

no. of images= _____360°________

angle between mirrors

Thus,

When angle between mirrors=45°

Then,

no. of images= 360°/45° - 1 = 8-1=

And when,

angle between mirrors=30°

Then,

no. of images= 360°/30°-1 = 12-1=11

And when,

angle between images=60°

Then,

no. of images = 360°/60°-1 = 6-1 = 5
