A surveyor is trying to find the length of a lake. He finds a baseline distance AB of 125 m. Angle A is measured to be 41.6° and angle B is measured at 124.3°. Find the length of the lake d. Please and Thank you.

Step-by-step explanation:

See attachment for question illustration

From the attachment, we have:

Required

Solve d

First, we need to calculate <C

--- angles in a triangle

Make <C the subject

Next, we apply Sine's law to solve for d

In this case:

Make d the subject

Hence, the base of the lake is approximately 340.7m

is only a line? i think so

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
