She spent 21 minutes completing the math problems. But then you add the 9 minutes she spent checking. Your answer is 30 minutes in total
The answer is 18/5 and simplify that and u get 3 3/5.
(-23,-11) is the other endpoint due to (a+b/2)
The measure of the angle FEG is probably the same as the measure of the angle FDG. There is nothing saying that EF is parallel to DG, but if so, the measure of the angle FEG is also 50º.
When the diagonals of a trapezium with two parallel bases inside of a circle are drawn, they make the same angle measure with those bases.
Using the quadratic formula, the answers could be A B and D
