Find the slope and y-intercept of the line that is perpendicular to y=-2/3x+5 and passes through the point (5,7).

4.28095238095 that is the answer

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is
