Answer:
0
Step-by-step explanation:
3(r+300)=6
Divide each side by 3
3/3(r+300)=6/3
(r+300)=2
Now we want to find
r+300-2
2 -2
0

Answer:
Step-by-step explanation:
Her angle of depression is the same measure as the angle of inclination inside the triangle. That's the base angle that is not the right angle. The height of the triangle is the 10,000 feet she is up in the air, and the reference angle is 20, and we are looking for the measure of the base of this right triangle. The trig ratio that uses the side opposite over the side adjacent is the tangent ratio:
and
so
x = 27474.77 feet
Answer: y=2
Step-by-step explanation:
2x+3y=14 - 2x-y=6 = 4y=8
y=2
If you need x, just insert y into the equation and work out x from there
2x-2=6
2x=8
x=4
