Answer:
c,=2d=-2
Step-by-step explanation:
The triangle to the top right is missing one angle. We know the sum of all angles in a triangle add up to 180 degrees. We already have 35 + 90 = 125 degrees, so the last angle must be 55 degrees. That angle is verticle to another angle, which you should be able to notice (also 55 degrees because vertical angles are congruent). Now, we have 67 + 55 = 122 degrees in that triangle. It must add up to 180, so the unknown angle is 58 degrees.
Answer:
4
Step-by-step explanation:
The square root of a number is the same number multiplied by itself. In the case of 16, 4x4 equals 16. So 4 is being used twice making it the square root of 16.
I think it will be because if you multiply 1/2 times 4/5 it will be 0.4
#5.
First you divide 200 miles by 5, then multiply that number by 7.
Why?
You have to find out how many miles one inch represents to know how many miles 7 inches is.
#6.
Divide 48 by 6, then multiply that number by 3.
Why?
For every 6 yards of material, 3 yards of trim is used to make one costume. So when you divide 48 by 6, you find out how many yards of material us needed to make ___ costumes. Multiplying ___ by 3 will show how many yards of trim she needs.
I hope this helped. Im really bad at finding rules sorry.
