PLSS HURRY IM ON A TIME LIMIT! Use the given measures of A and B to answer the following questions.
mA = 20°
mB = (2x)

Part A Write an equation when ZA and ZB are vertical angles. Solve the
equation for x, showing your work. What is the measure of ZB?

Part B Write an equation when ZA and ZB are complementary angles. Solve the equation for x, showing your work. What is the measure of B?

Part C Write an equation when A and B are supplementary angles. Solve the equation for x, showing your work. What is the measure of B?​

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
