How do you get the measurements of an angle

Tim's phone service charges $23.06 plus an additional $0.22 for each text message sent per month. if tim's phone bill was $28.56, which equation could be used to find how many text messages, x, tim sent last month?

The quadratic function y = -x2 + 10x - 8 models the height of a trestle on a bridge. the x-axis represents ground level. to find where the section of the bridge meets ground level, solve 0 = -x2 + 10x - 8. where does this section of the bridge meet ground level? choose an equation that would be used to solve 0 = -x2 + 10x – 8 (x + 25)2 = –8 (x – 5)2 = 17 (x – 10)2 = 25 solve the equation to find where the trestle meets ground level. enter your answers from least to greatest and round to the nearest tenth. the trestle meets the ground at units and units.
