Find the measure of angle X.
Alik [6]

The triangle is an isosceles triangle so that means the base angles must be congruent.

The sum of the interior angles of a triangle add up to 180 degrees.

Subtract 52 degrees from 180 degrees.

180 - 52 = 128

Divide 128 degrees by 2.

128/2 = 64

m∠X = 64°

Licemer1 [7]

The formula for the future value A, given annual interest rate r, number of years t, and deposit amount P can be written as

... A = P(1 +r/12)((1+r/12)^(12t) -1)/(r/12)

Filling in the given numbers, you have

... A = 200(1+.0275/12)((1+.0275/12)^(12·39) -1)/(.0275/12) ≈ 167,868.30

The appropriate choice is $167,868.30.
