Answer:
m∠T = 45°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
∠S + ∠T + ∠U = 180°
2x + 10 + 3x - 9 + 6x - 19 = 180
11x - 18 = 180
11x = 180 + 18
= 198
x = 198 ÷ 11
x = 18
m∠T = 3x - 9
= 3(18) - 9
= 54 - 9
m∠T = 45°
We are given the coordinate of the 3 vertices. From these coordinates we can find the length of the sides using the distance formula and the sum of all the sides will be equal to the perimeter of the triangle.
Side PQ =
Side QR =
Side RP =
So, the perimeter of the triangle will be 8 + 4.5 + 7.2 = 19.7
You probably misplaced the digits in option A. The correct answer is 19.7 units.

Answer:
$5426.45
Step-by-step explanation:
Using the formula
APY= P(1+
P - principal
r - interest rate
n - number of compound periods
t- time
APY = 4500(1+.0125/4)^60 = $5426.45
