step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45

the answer is a

step-by-step explanation:

multiply by the conjugate

the conjugate is the bottom express (6-√13) with the middle changed to +

or (6+√13)

so times it be   (6+√13)/(6+√13)
