Find the measure of each angle. m∠bac= m∠cad=

i dont have much time to go through all the work but i can tell you that since its a 90 degree angle, your equation would be 90=15x-2+7x+4. Once you get the value of X plug that into each of the equations. For example if your x value was 2 you would do 15(2)-2. Thats just an example.

i dont know

step-by-step explanation:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
