What are the coordinates of the image of ABC after a dilation with center (0, 0) and a scale factor of 3?

If the measure of angle 1 is 110 degrees and the measure of angle 3 is (2 x+10 degree), what is the value of x?

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

Given: circle o, cd is diameter, chord ab || cd. arc ab = 74°, find arc ca.
