Question

Example 4. If angle B and angle Q are acute angles such
that sin B = sin Q, then prove that , angle B= angle Q.
[NCERT SOLVED EXAMPLE]​

Answer 1

cancel the 'sin' you get Q = B.

another way of solving is googling the question or you can also try listening to your teacher in class

p.s. I know i'm right

Answer 2

Step-by-step explanation:

let's take two right angle triangles ABC and PQR. sinB= side opposite to B by hypotenuse, sinQ = side opposite to Q by hypotenuse, then Sin B = AC by AB , SinQ = PR by PQ then Sin B =sinQ so AC by AB =PR by PQ
