4. Use trigonometric ratios to solve for the variable. Show your work. Round lengths to the nearest tenth and angles to the nearest whole degree. 7 5 7 JS

y = 1.9 units (nearest tenth)

Step-by-step explanation:

recall that for a right triangle with angle θ

tan θ = opposite length / adjacent length

in our case we are given the following:

θ = 15 deg

opposite length = y

adjacent length = 7

substituting these into the equation:

tan θ = opposite length / adjacent length

tan 15 = y / 7

y = 7 tan 15

y = 1.8756

y = 1.9 units (nearest tenth)

answer: 59
