The solution is r= 7/a-x How did i do this?
Your equation is ax+ r=7, so the goal is to isolate the r. You begin by dividing the a from the ax. Remember, what you do to one side, you must do to the other. So you do 7/a, since you can't simplify 7/a, leave it as it is. Next, your equation should look like this x+r=7/a. In order to isolate the r, you move the x to the other side by subtracting, which leaves you with the answer of r= 7/a-x.

Formula for trapezoid
A=h*(b1+b2)/2,
b1 an db2 are the two lengths of the sides
152 = 16*(b1+6)/2 = 8*(b1+6)=8*b1+48--> 8*b1=104, b1 = 104/8=13
A = 16*(6+13)/2=16*9.5=152
The measure of an inscribed angle is half the intercepted arc. 30 degrees is the answer. I hope this helped you! Have a fantastic day!
