Answer:
V=6
Step-by-step explanation:
Step 1: Subtract 25 from both sides.
4/3v+25-25=22-25
4/3v=8
Step 2: Multiply both sides by 3/4
(3/4)*(4/3v)=(3/4)*(8)
v=6
Answer:
The measure of angle LKJ is 49°
Step-by-step explanation:
<u><em>The correct question is</em></u>
The equation tan−1 = {8.9/7.7} x can be used to find the measure of angle LKJ. What is the measure of angle LKJ?
Round to the nearest whole degree.
see the attached figure to better understand the problem
Let
x -----> the measure of angle LKJ
we know that
so
using a calculator
Round to the nearest whole degree
therefore
The measure of angle LKJ is 49°
he equation of any horizontal line is
y = .. a number
The x-value has no effect on the equation or on the line at all, as long as y-value stays the same.
In this case the line passes though the point (−8,9)
which tells us that the y-value we want is 9.
Therefore the equation is y=9

Answer:
5507.79 feet
Step-by-step explanation:
To find the height of the mountain, we can draw triangles as in the image attached.
Let's call the height of the mountain 'h', and the distance from the first point (31 degrees) to the mountain 'x'.
Then, we can use the tangent relation of the angles:
tan(34) = h/x
tan(31) = h/(x+1000)
tan(31) is equal to 0.6009, and tan(34) is equal to 0.6745, so:
h/x = 0.6745 -> x = h/0.6745
using this value of x in the second equation:
h/(x+1000) = 0.6009
h/(h/0.6745 + 1000) = 0.6009
h = 0.6009 * (h/0.6745 + 1000)
h = 0.8909*h + 600.9
0.1091h = 600.9
h = 600.9 / 0.1091 = 5507.79 feet
