Explain how you calculated your answer Angle a = 126 degrees Write an equation (s) in terms of to find the measure of angle h. Calculate the measure of angle h using the equation (s ) you wrote for Part How would knowing the measure of angle y change the equation(s) you wrote in Part B find the measure angle h

On a coordinate grid, point p is at (4, 3) and point r is at (−2, −5). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s? q(−4, 3), s(2, −5) q(4, −3), s(−2, 5) q(−4, −3), s(2, 5) q(−4, 3), s(−2, 5) ; -; i can't figure it out, if someone can me with the answer,that would be nice

Δabc is dilated by a scale factor of 3 with the origin as the center of dilation to form δa′b′c′. the slope of is -1.2. the length of is p units, the length of is q units, and the length of is r units. the slope of is . the length of is units.
