Answer will be 160 Degree. As per the rule, that angle subtended by any arc at the center will be double of the angle subtended by the same arc at the remaining part of the circle.
Here in example the minor arc CA will subtend 160 degree at the center which is double of the angle 80 degree as it is subtended by the same arc at the remaining part of the circle.

Answer:

When you fill in the blanks you get ($0.25*x)+(0.1*y)+(0.05*z). When you evaluate it you get $1.35, which is the total amount of change in her pocket.

Step-by-step explanation:

All of the numbers that are given in the equation are values of the coins (ex: a quarter is worth $0.25) and the variables are the different coins. Multiply the quantity of each coin (that's the variable) by its value then add them together. Finally, plug in the numbers it gives you for x, y, and z.
