Ms. J used an app on her phone and measured the angle of elevation to the top of a mountain and found it to be 15°. She then drove 5 miles closer to the mountain and again measured the angle of elevation. Now it was 56°. Assuming she drove along a straight, flat road. What is the height of the mountain? Round your answer to the hundredths place and label appropriate units.

i think the answer is b)

step-by-step explanation:

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

thats not a system of equations, that is a solution
