Question

2. PQRS is a square and PQT is an equilateral triangle on the side PQ of the
square, angle SPT=
a)45° b) 40° C) 30° d) 15°​

Answer 1

We know that, each angle of a square is 90°

Also, the measure of each angle of an equilateral triangle is 60°[ by angle sum property]

Therefore, the measure of angle SPT

=90°-60°

= 30°

Therefore, option no. C is correct.
