Please hurry find the measure of P

Inessa [10]

Answer:

m∠P = 65°

Step-by-step explanation:

An Isosceles triangle has two sides of equal length and two interior angles of equal measure.

Sum of interior angles of a triangle = 180°

If QO ≅ PQ and the enclosed m∠Q = 50° then m∠P ≅ m∠O

⇒ m∠Q + m∠P + m∠O = 180

⇒ 50 + m∠P + m∠O = 180

⇒ m∠P + m∠O = 130

As m∠P ≅ m∠O:

⇒ m∠P = 130 ÷ 2 = 65°

ivolga24 [154]

Answer:

0.2682 or 26.82%

Step-by-step explanation:

The monthly interest rate (r) that your friend is willing to pay is:

$r=\frac{1}{50}=0.02$

The following expression converts a monthly interest rate (r) into an annual interest rate (i):

$r=\sqrt[12]{1+i}-1$

For r = 0.02:

$0.02=\sqrt[12]{1+i}-1 \\1.02^{12}-1=i\\i=0.2682$

Your friend is willing to pay an annual rate of 0.2682 or 26.82%.
