Angles 2 and 4, and Angles 3 and 5 are supplementary. Supplementary means two angles add up to 180 degrees (aka a straight line).
Answer:
Your answer is 2 1/2.
Step-by-step explanation:
Divide 9 pounds of sand into 4 buckets, or 9÷4. This equals 2.5 pounds of sand in each bucket.
Answer:
Part A: 4x = -5(x-18)
Part B: A and B both = 40 degrees
Step-by-step explanation:
Ok, corresponding angles are in the same position on the two parallel lines cut by the transversal. And they are equal in measure. So, upper right = upper right.
So A = B
4x = -5(x -18)
4x = -5x + 90
9x = 90
x = 10
Angle A = 4x = 40 degrees, which means angle B is also 40, but let's show the work:
Angle B = -5(x - 18) = -50 + 90 = 40
