In △pqr, find the measure of ∡p.
triangle pqr where angle q is a right angle. qr measures 33 point 8. pq measures 57 point 6. measure of angle p is unknown.
30.4°
35.9°
54.1°
59.6°

m∠p=

step-by-step explanation:

we know that

in the right triangle pqr of the figure

in this problem we have

substitute the values

step-by-step explanation:

if x = 2 you have to find x to finish the problem

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
