You want to be finding out what two factors (where one of them is a perfect square) has the produce of 63. It seems like 9 x 7 (9 is the perfect square) works.

The square root of 9 is 3 so we can just have

(which just means 3 times the square root of 7).
Answer:
51,040
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>The scale is </u>
- 15 in ÷ 24 feet =
- 15 in ÷ 24*12 in =
- 15 in ÷ 288 in =
- 5 in ÷ 96 in =
- 5 ÷ 96
It d because one x-value correspond two different y-values
Answer: D. 44
Step-by-step explanation:
Here, we need to know the concept of trigonometry.
- Sine (sin) = Opposite/Hypotenuse = O/H
- Cosine (cos) = Adjacent/Hypotenuse = A/H
- Tangent (tan) = Oppostie/Adjacent = O/A
-----------------------------------------------------------------------------
Given
- The adjacent side of angle x and the hypotenuse.
- We are going to use Cosine.
<u>Solve</u>
cos (x) = 15/21
x = cos⁻¹ (15/21)
x ≈ 44
Hope this helps!! :)
