Answer:
B = 22
C = 122
D = 36
Step-by-step explanation:
The angles of a triangle add to 180. Take the measure of each angle add them together. Set them equal to 180.
2x + x + 4 + 7x - 4 = 180
10x = 180
x = 18
To find each angle, substitute x = 18.
Angle B is 18 + 4 = 22
Angle C is 7(18) - 4 = 122
Angle D is 2(18) = 36

Answer:
$2,221.6 monthly
Step-by-step explanation:
A = P(1 + r)^n
A is the total amount I intend to save = $15,000
r is the yearly interest rate = 3.6% = 0.036
n is the duration to achieve my goal = 4 and 1/2 years = 54 months
15,000 = P(1 + 0.036)^54
15,000 = P(1.036)^54
P = 15,000/6.752 = 2,221.6
I need to put $2,221.6 into the savings account monthly
