Two ponds can be seen from a tower. The angles of depression to pond A and Pond B are angle 12 degrees and angle 19 degrees respectively, form a height of 22m on the tower. The measure of the angle between the lines of sight to the ponds is angle 78 degrees. Find the distance between the ponds.

answer: d. $20

step-by-step explanation:

just took the test

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
