We know that all three angles in a triangle must add to 180 degrees so we can use this fact to find the measure of the missing angles.
180-57-101= 22 degrees
180-72-72=36 degrees
180-x-20=160-x degrees
Answer:
5
+40
Step-by-step explanation:
perimeter of circle=2
r
so 5 is r(radius)
so 10
, but since it’s semicircle, you have to divide by 2, so
5
perimeter of rectangle=15+10+15 because you don’t count the inside, so that equals 40
so 5
+40
The answer is A. (2,2)....
Answer:
$11.25
Step-by-step explanation:
Multiply the number of hours she works by how much she gets paid per hour.
800
Multiply 50 times 7 (50 being the amount charged for her kid and 7 being the days of the week)
350
Subtract the 350 from the 800
450
Divide the 450 by the number of hours worked per week
450/40
Answer: 11.25
So Sally actually makes 11.25 per hour.
