Hope it helps :) sorry if the answer is wrong
Angle A and angle B are supplementary. The measure of angle A is 4 less than 7 times the measure of angle B. Find the measure of

notice... a derivative is just the function for the slope
now, you're given the point 3,1, namely x = 3 and y = 1
to find the "m" or slope, use that derivative, namely
that'd give you a value for the slope
to get the tangent line at that point, simply plug in the provided values
in the point-slope form
and then you solve it for "y", I gather you don't have to, but that'd be the equation of the tangent line at 3,1
Answer:
7949.13 feet
Step-by-step explanation:
We are given that,
Angle of depression from the spot to the group = 39°
Height of Grand Canyon = 5000 feet.
So, we will get the following figure of a right triangle.
<em>As, 'in a right triangle, the angles and the sides can be written in trigonometric form'.</em>
We get,
i.e.
i.e.
i.e.
i.e. x = 7949.13 feet
Thus, the line of sight distance is 7949.13 feet.
