Two observers on the ground 1.5 mi apart see a helicopter in the air directly between them. The angles of elevation from the observers to the helicopter are 30° and 35°.
Find the altitude of the helicopter.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

if the probability is 1/12, 75 people will receive a $25 gift card
