SOMEONE PLEASE EXPLAIN THIS TO ME

P = 46.40°

Step-by-step explanation:

Since this is right triangle where all the sides are known we can use either sine, cosine or tangent of the angle to solve for P. Let use sine:

sin P = opp/hyp

= 21/29

or

P = arcsin(21/29) = arcsin(0.724)

= 46.40°

The answer is "all angle will be same"
