Q1
r = (2A/θ)^.5 = ((14/(1/8))^.5 = 10.583 ft <--------
q2
θ = 2A/r^2 = 2*3/7^2 = .122 rad <--------
455, because if you do 5/12=0.416666..., and then you multiply that to 780 you would get 325, and then you do 780-325 to equal 455.
present value of annuity = annual payment * [ 1 - (1+i)^-n ]/i
=>
12500 = 128.04 * [1-(1+9%/12^-n]/9%/12
=>n = 42 payments
Answer:6
Step-by-step explanation:
Answer:
103
Step-by-step explanation:
This shape is pentagon.
Note : -
Sum of interior angles of a pentagon is 540.
115 + 105 + 117 + 100 + x = 540
437 + x = 540
x = 540 - 437
x = 103
