When something is bisected, it is cut in half. <RTS is cut into two equal halves, <VTS and <RTV.
<VTs = <RTV
Let's plug the numbers from our problem into the equation above.
16x - 6 = 13x + 9
Add 6 to both sides and subtract 13x from both sides.
3x = 15
Divide both sides by 3
x = 5
Let's plug 5 into x for <RTV
m<RTV = 16(5) - 6 = 80 - 6 = 74 degrees
In conclusion,
x = 5, m<RTV = 74 degrees
