I think it would be B but i am not 100% sure.
Answer:
4 hours
Step-by-step explanation:
Danielle spent 4 hours painting. You can get this answer by subtracting how much money she spent on the pot from the total bill. This gets you 24. Then you divide this by 6, the amount of money if costs to paint an hour, which gets you 4.
Given:
m∠ABC = 118°
m∠DAC = (9x - 33)°
m∠CAB = (2x + 7)°
To find:
The value of x.
Solution:
Sum of the adjacent angles in a parallelogram = 180°
m∠ABC + m∠CAB + m∠DAC = 180°
118° + 9x° - 33° + 2x° + 7° = 180°
92° + 11x° = 180°
Subtract 92° from both sides.
92° + 11x° - 92° = 180° - 92°
11x° = 88°
Divide by 11° on both sides.
x = 8
The value of x is 8.
Y = x² + 2x - 8
which two numbers add up to 2 and multiply to -8?
-2 and 4
so rewrite the expression using the above;
(x - 2)(x + 4)
x = 2, -4
so the zeros are 2 and -4.
hope this helps, God bless!

Answer:
42.9 ft
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
where Opposite in this case is the height of the tree, and Adjacent is the distance to the tree.
tan(47°) = height/(40 ft)
height = (40 ft)·tan(47°) . . . . . multiply both sides by (40 ft)
height ≈ 42.9 ft
The tree is about 42.9 feet tall.
