Answer:
Step-by-step explanation:
Given:
Right ∆ with,
Hypotenuse = x
Opposite = 9
Reference angle 
= 39°.
Required:
The value of x
Solution:
Since we are given a reference angle with opposite length, and we are to find the hypotenuse length, x, apply the following trigonometric ratios formula:
Plug in the values into the equation
Multiply both sides by x
Divide both sides by sin(39)
(to 2 decimal places)
23-9=14
24-10=14 BOTH EQUASTIONS ARE EQUAL
Answer:280 square feet per hour.

Answer:
i think its either a or b
Step-by-step explanation:
Answer:
x=14
Step-by-step explanation:
Since the triangles are similar, you first line up the sides. Then, because the 16 and the 24 line up together, you divide them to find out how much bigger the first triangle is, which is 3/2 or 1.5. After that, you can see that the 21 and the x are on the same side, so you would divide 21 by 1.5 or 3/2 to get x. 21÷1.5=14.
x=14
