Answer:
I think it is 130 but I could be wrong... BUT I LOVE GOLF!!!
Answer:
108
Step-by-step explanation:
x = (n - 2)180/n
n = 5
x = (3)(180)/5
x = 108
Answer:
x ≈ 41.4°

- Law of Cosines: c² = a² + b² - 2(a)(b)cosC°
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
C° = x°
c = 12
a = 15
b = 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [LC]: 12² = 15² + 18² - 2(15)(18)cosx°
- Exponents: 144 = 225 + 324 - 2(15)(18)cosx°
- Add: 144 = 549 - 2(15)(18)cosx°
- Multiply: 144 = 549 - 540cosx°
- Isolate <em>x</em> term: -405 = -540cosx°
- Isolate <em>x</em> term: 3/4 = cosx°
- Isolate <em>x</em>: cos⁻¹(3/4) = x°
- Evaluate: x = 41.4096°
- Round: x ≈ 41.4°
To find the amount of work done, we need to use the formula for work.
The formula is: Force x Distance.
The force being given is 50N, and the distance traveled is 3M.
With this information, we're ready to solve!
Let's plug in our numbers to the formula given above.
Work = 50 x 3
50 x 3 = 150.
The amount of work done is 150J.
I hope this helps!
