Question

Q1 In the below diagram, angle of reflection and angle q will be?
!
56°

(a) Angle r=42°, Angle q=22°
(b) Angle r=43°, Angle q=550
(c) Angle r=34°, Angle q=56°
(d) Angle r=390, Angle q=450​

Answer 1

Answer:

(c) Angle r=34°,Angle q= 56°

Answer 2

Given: From the given figure one angle is given as $56$°.

We have to find the angle of reflection and angle $q.$

The given problem is solved in the following way,

From the given figure we can say that,

$=>i=90-56\\=>i=34$

So, angle $i=34$°

Hence, from the law of reflection, we can say that,

Angle $i=r=34$°

Now,

$=>q=90-r\\=>q=90-34\\=>q=56$

So, angle $q=56$°

Hence, Angle $r=34$°, Angle $q=56$°

Option c) is the correct answer.
