Answer:
x = 26.4
Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
Basic trigonomic ratios (θ is the reference angle):
- Sine θ = opposite / hypotenuse
- Cosine θ = adjacent / hypotenuse
- Tangent θ = opposite / adjacent
Given the diagram, we can see that the reference angle is x. We are also given the hypotenuse (9) and the opposite side length (4). With the opposite and the hypotenuse, we know that we need to use the sine ratio:
sin(x) = 4/9
To solve for an angle given the side lengths, we use the inverse functions:
x = sin^-1 (4/9)
x = 26.4
I hope this helps!
Answer:
Step-by-step explanation:
126 mi/h = (126 mi)/(1 h)·(5280 ft)/(1 mi)·(1 h)/(3600 s) = (126·5280/3600) ft/s
126 mi/h = 184.8 ft/s = 924/5 ft/s

In 2 seconds, the parachutist falls ...
(184.8 ft/s)·(2 s) = 369.6 ft
Tell me the two names of the properties.
Like the two of them
<span>First set: 7, 24, 25.
Square 7, 24 and 25.
Add together the squares of 7 and 24.
Compare this sum to the square of 25. </span>
<span>To get my answer, I multiplied
$2075 by 0.3 to get 622.50. Then I subtracted 622.50 from 2075 to get
1452.50.
