Answer:
h ≈ 448.0 m
Step-by-step explanation:
The relevant trig function is the one that relates adjacent side length, opposite side length, and angle:
Tan = Opposite/Adjacent
Solving for the adjacent side length, we get ...
Adjacent = Opposite/Tan
For the two angles given, we want the value of the difference of the adjacent side lengths:
168 m = h/tan(41.2°) -h/tan(52.5°)
Then h is found by dividing by its coefficient:
h = (168 m)/(1/tan(41.2°) -1/tan(52.5°))
h ≈ 448.0 m
Answer:
The answer is 68 and 52
Step-by-step explanation:
x + y = 120
3(x - y ) = 48
We have 3x + 3y = 360
and 3x - 3y = 48
Adding we have the following:
6x = 408
x = 68
y = 120-48 = 52
Answer:
(4,11)
Step-by-step explanation:
y=2x+3
y=5x-9
the first equation is equal to the second equation so
2x+3=5x-9
put like terms together
2x-5x= -9-3
-3x= -12
divide both sides by -3
.•.x=4
now, use the value of x to find the value of y like this:
y=2x+3 (x=4)
y=2(4)+3
y=8+3
y=11
therefore, the two lines intersect at the point (4,11)
