Cos (known angle) = adjacent leg / hypotenuse ( distance wanted)
cos(50) = 14 / x
x = 14 / cos50
x = 21.78 feet
The problem doesn't say if the answer should be rounded or not. You may have to round the answer if needed.
You are given the "side" opposite the angle. souse the SOH part Sine=opposite/hypotenuse
so when you plug in the information you get this equation:
sin(50)=14/x
divide both sides by sin(50) and you should get
a hypotenuse of approx. 18.3

The complete question is
Find the percent of change. Round to the nearest tenth if necessary.
25 points to 50 points .
Notice that this change is an increase, to fint the percetange of change, we just need to divide and then multiply by 100 to have it in percetange expression:
So, the percentage of change is 100%, because the change is 25, that was the increase.
125 invitations to 75 invitations .
Which means 75 invitations represents 60% of the old number of invitations.
So, the percentage of change is 40%, because that's the percentage of the difference.
32 pages to 28 pages .
You can do another process, first find the difference:
Then, you divide:
So, the percentage of change is 12.5%.
7 players to 10 players.
So, the percentage of change is around 43%.

What are radicals in math?
Radicals in math refer to expressions containing square roots or higher-order roots.
Represented by the radical symbol (√), they involve finding the root of a number. For example, √9 equals 3, as 3 * 3 equals 9.
Simplifying the surd;
√3c²)/√27
= √3 × √c²)/√9 × √3
= √3c/3√3
= c/3
Therefore the simplification of √3c²)/√27 is c/3.

The equation of a perpendicular bisector is thus:
.
Hope this helps.
Answer:
Step-by-step explanation:
Using the given points, first find the slope:
m = (₂ - y₁) / (x₂ - x₁)
= (5 - 9) / (-1 - (-3))
= -4 / 2
= -2
Find y-intercept by using anyone of the give points and slope from above:
y = mx + b
5 = -2(-1) + b
5 = 2 + b
b = 3
With the m and b, you can make equation of line:
y = mx + b
y = -2x + 3
To find the perpendicular slope, make it opposite and inverse it.
m = -2 becomes 1/2
Regular equation of line:
y = -2x + 3
