Answer:
x = 2.8
y = 2
Step-by-step explanation:
Reference angle = 45°
Opposite = 2
Hypotenuse = x
Adjacent = y
✔️To find x, apply the trigonometric function SOH:
Sin 45 = Opp/Hyp
Sin 45 = 2/x
x*Sin 45 = 2
x = 2/Sin 45
x = 2.82842712 ≈ 2.8 (nearest tenth)
✔️To find y, apply the trigonometric function TOA:
Tan 45 = Opp/Adj
Tan 45 = 2/y
y*Tan 45 = 2
y = 2/Tan 45
y = 2
First, find the difference in values:
2075-1195=880
Now, divide the difference by the original price and multiply by 100:
(880/1195)×100=73.6= 74% is your answer
To check, simply do 1195×1.74=$2079.30, the answer changes slightly due to rounding.
Answer:
81/16
Step-by-step explanation:
We have [(3^2 * 5^0) / 4]^2
= [ ( 9 * 1) / 4]^2
= (9/4)^2
= 81/16
Answer Answer Answer Answer
The problem ask to calculate and find the value of cos(2npi). So base on the data you have given, we must follow the theories and rule of simplifying and calculating trigonometric expression, so base on that, the answer would be that the cos(2pi) is equals to 1 so the cos(2npi) if even =1 if odd =-1. I hope you are satisfied with my answer and feel free to ask for more
