Question

Math determine and explain

Answer 1

p=21.4

P= 44.43 degrees

Explanation:

This is Pythagorean's theorem! Remember a^2+b^2=c^2

so with our numbers, c=30, b=21, and we need to solve for a...

a^2+21^2=30^2

a^2=30^2-21^2

a=sqrt(30^2-21^2)

so...

a= 21.4 cm (rounded to the tenth)

now for the angle P, lets use some trig

we know that sin(P)=21/30

so we can determine that

P=arcsin(21/30)

P= 44.43 degrees
