If r is the midpoint of qs, rs=2x-4, st=4x-1, and rt=8x-43, find qs

Step-by-step explanation:

Look at the picture.

We must start from domain:

   add 4 to both sides

    divide both sides by 2

and

         add 1 to both sides

         divide both sides by 4

and

           add 43 to both sides

          divide both sides by 8

From 1, 2 and 3 we have:

R is midpoint of QS. Therefore QR = RS ⇒ QS = 2(RS).

RS = 2x - 4

Put the value of x and calculate the length of RS:

Therefore

the radius is 2 times the diameter.

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
