Answer:
f = 
Step-by-step explanation:
1. 4(4f - 9) = -(2-f) distribute the negative
2. 4(4f - 9) = -2 + f Distribute the 4
3. 16f - 9 = -2 + f Subtract f on both sides
4. 15f - 9 = -2 Add 9 on both sides
5. 15f = 7 Divide both equations by 15
6. 
f =
The answer is c because it makes the most sense
Answer:
Venom C is 0.625 times as potent as venom A.
Step-by-step explanation:
We are given that venom A is four times as potent as venom B.
Venom C is 2.5 times as potent as Venom B.
We have to find that how many times as potent is venom C is compared to venom A.
Let Venom B =x
Then Venom A=
Venom C=
Hence, venom C is 0.625 times as potent as venom A.
The angle of depression from the top of the flag pole to point A is 36.2 degrees.
<h3>What is the angle of depression?</h3>
From trigonometric ratio: cos(θ) = Adjacent / Hypotenuse
Given that;
- Adjacent = 25ft
- Hypotenuse = 31ft
- Angle of depression θ = ?
cos(θ) = Adjacent / Hypotenuse
Cos(θ) = 25ft/31ft
Cos(θ) = 0.80645
θ = cos⁻¹( 0.80645 )
θ = 36.2°
Therefore, the angle of depression from the top of the flag pole to point A is 36.2 degrees.

Answer:
The angles are 24° and 66°.
Step-by-step explanation:
Let two angles be x and y.
For two complementary angles,
x+y = 90 ...(1)
ATQ,
x-y = 42 ...(2)
We need to find the measures of the angles.
Add equation (1) and (2).
x+y+x-y = 90+42
2x = 132
x = 66
Put the value of x in equation (1)
66+y = 90
y = 90-66
y = 24
So, the angles are 24° and 66°.
