4.75 feet, because you would multiply 5 by 1.54 which gives you 7.25 subtract that from 12
First vector orthogonal<span> to ⟨−</span>3<span>,4</span>
Answer:
Pretty sure it's 20.24.
Step-by-step explanation:
Since you know the side adjacent to the reference angle and you want to find the side opposite, you're going to need to use tangent, which is opp/adj.
tan(39) = 
Find the tangent of 39...
0.8097 is the approximate value. So...
0.8097 = 
Now, switch the sides to make it easier.
= 0.8097
Multiply both sides by 25.
x = 20.24
