It depends because u have to show us the diagram since we have to know if it is opposite or adjacent to the angle! Anyways I think u can solve it on your own! The question might have something to do with trigonometry like cos sin and tan! Remember the area of a triangle is 1/2*base*height
Answer:
175 ft
Step-by-step explanation:
Let c represent the change in altitude. Then an equation can be written:
150 +c = 325
We solve for c by subtracting 150 from both sides of the equation:
c = 325 -150 = 175
The change in altitude is an increase of 175 feet.
_____
This confirms the general rule that to find the value of a change, you subtract the original value from the new value. Here, that means ...
c = 325 -150 = 175 . . . . as above.
Answer:
36 degrees
Step-by-step explanation:
There's 180 degrees in a triangle.
Since they're supplementary angles, we do 180-142=38.
We now know that 106+38+x=180.
Solve for x: x=36

Answer:
x = {2π/3, 4π/3}
Step-by-step explanation:
The equation can be factored as ...
(cos(x) +3)(2cos(x) +1) = 0
The solutions are the values of x where the factors are zero.
cos(x) +3 = 0
cos(x) = -3 . . . . . . no real solution
__
2cos(x) +1 = 0
cos(x) = -1/2
x = arccos(-1/2) = 2π/3
The other solution in the desired interval is ...
x = 2π -(2π/3) = 4π/3
The solutions are x∈ {2π/3, 4π/3}.
