Answer:
127.3 ft
Step-by-step explanation:
Make it a right triangle...
ΔABC is 90 by 90 by x
x = 
x = 
x = 
x = 127.3 ft
Answer:can i get brainiest anyway
Step-by-step explanation:
Remember:
sin²x + cos²x = 1
(-5/13)² + cos²<span>θ = 1
(25/169) + cos²</span><span>θ = 1
cos²</span><span>θ = 1 - (25/169)
cos²</span><span>θ = (144/169)
tan </span>θ > 0 ⇒ cos<span>θ = negative
cos</span>θ = -√(144/169)
cos<span>θ = -(12/13)</span>
Answer:
Sine is equal to opposite over hypotenuse in right triangles. Let's say we have a 3-4-5 right triangle, the side opposite the 90° angle is 5, and 5 is also the hypotenuse. 5/5 = 1
Therefore, in all right triangles, the side opposite the 90° angle is equal to the hypotenuse, and anything over itself is equal to one.
(Not sure if this is a mathematically correct way to explain it, but it makes the most sense to me.)
So there are 8 students, therefore each student gets 1/8 of
the cake.
Since only 3/4 of a cake is available, they will each get
1/8 of 3/4.
We can find this by
multiplying 1/8 and 3/4.
To get the answer, we multiply the numerators together and
the denominators together which gives us:
(1*3)/(8*4) = 3 / 32 = 0.09375
So each student only get 3 / 32 of the cake.
