Answer:
40.3 feet
Step-by-step explanation:
Use trigonometry.
First, set your calculator to Degrees instead of Radians. Next, draw a model like the attached image to help you better understand the question.
Now, figure out which trigonometric ratio to use. In this case, it is easiest to use sine (or cosine).
sin(38°) = x / 125
125(sin(38°)) = x
x ≈ 37.046
Finally, to find the height, simply add how high the hand is from the ground:
h = 37.046 + 3.25 = 40.296
So,
h ≈ 40.3 ft
Answer:
1st one, 4th one, and 5th one
Step-by-step explanation:
This is a good one!
So we know that a triangle's angles must add up to 180 degrees. Therefore, we can say that:
(3x - 3) + (5x + 3) + (4x) = 180.
This can be rewritten as 12x = 180.
Divide each side by 12 to get x alone, you get:
x = 15
Time to plug n' chug.
4x = 60, 3x - 3 = 42, 5x + 3 = 78
Boom!
Answer:
4^-10
Step-by-step explanation:
(4^-2)^5
4^-2 x 5
= 4^-10
hope this helped have fun doing school haha
The answer is -2 for the csc and it’s also a rational denominator
