Help my last question and I'm done A. What is the sum of all the interior angles in the kite?

B. Copy the kite and draw the diagonals. What is the measure of the angle at which the diagonals intersect?

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6

How many solutions does the nonlinear system of equations graphed below have? a. one b. zero c. four d. two

I’m really confused and need to learn this
