The angle the beam makes with the pool surface is 29.72°.
Step-by-step explanation:
<u>Data:</u>
The spotlight and surface of a swimming pool makes a 90 degree angle.
Spotlight stand is 3m (Opposite)
Beam of light hits the water 7m away from the base of light (base)
Angle = ?
<u>Use sin to solve</u>
Formula:
Tan (Angle) = 
Solution:
Sin (Angle) = 
Angle =
(0.571)
Angle = 29.72°
Therefore, the angle the beam makes with the pool surface is 29.72°.

i can't help in number 12 , sorry !
Answer:
3 ≤ x ≤ 7 or x is between 3 and 7, inclusive
Step-by-step explanation:
Eira's graph probably resembled the diagram below.
The domain is the set of all possible x-values that will make a function work.
x can take any value from 3 to 7.
The domain is [3, 7] or 3 ≤ x ≤ 7.
The length of the hypotenuse is 5ft
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
c^2=25
sqrt c^2= sqrt 25
c=5
Therefore, the length of the hypotenuse is 5th
