Draw an imaginary line from the vertex of angle x to the center of the circle.
This divides the 4-sided polygon into two right triangles. For example, the upper right triangle has an acute angle whose measure is 135 degrees / 2, or 67.5 degrees, and the another acute angle whose measure is x/2.
x/2 and 67.5 degrees are complementary angles, so x/2 + 67.5 deg = 90 deg. Thus, x/2 = 22.5 deg, and so x = 45 deg. (answer)
Answer:
$2
Step-by-step explanation:
The price of each calculator is found by dividing the box price by the number of calculators in the box.
$30/5 -$32/8 = $6 - $4 = $2
In boxes of 8, each calculator costs $2 less.
First car: $10 + 3 every mile
Second car: $20 + 2 per every mile
For the part that says "Write an equation that represents the cost of
each car service and determine when they cost the same.", find the LCM of 13 and 22.
