Answer:
∠C = 75°
Step-by-step explanation:
using the formula for the sum of interior mangles for a polygon:
total interior angles = (180° x 5 angles) - 360° = 540°
113° + 4x + 113° + 2x + 9° + 3x + 8° = 540°
combine like terms:
9x + 243° = 540°
9x = 297°
x = 33°
∠C = 2(33) + 9 = 75°

Answer:
student pay interest = $247.5
future value is $3247.5
Step-by-step explanation:
Given data
principal = $3000
time period (t) = 9 months = 9/12 = 0.75 year
rate = 11.75 %
to find out
amount of interest and future value
Solution
first we calculate the future value by simple interest formula i.e.
future value = principal (1 + rate ×time ) ....................1
put all value rate, time principal in equation 1 we get future value
future value = principal (1 + rate ×time )
future value = 3000 (1 + 0.11 × 0.75 )
future value = $3247.5
student pay interest = future value - principal
student pay interest = $3247.5 - $3000
student pay interest = $247.5
