Answer:
I believe it would be C
Step-by-step explanation:
Answer: x = 23, y = 40
Step-by-step explanation:
By the same-side interior angles theorem, y+30 and 110 are supplementary.
- 110 + y + 30 = 180 [supplementary angles add to 180 degrees]
- y + 140 = 180 [combine like terms]
- y = 40 [subtract 140 from both sides]
We know that the 3x + 1 angle and y + 30 are also congruent, so:
- 3x + 1 = y + 30 [congruent angles have equal measure]
- 3x + 1 = 40 + 30 [substitute y = 40]
- 3x + 1 = 70 [combine like terms]
- 3x = 69 [subtract 1 from both sides]
- x = 23 [divide both sides by 3]
Answer:
37.5 sq in
Step-by-step explanation:
In order to find the actual width and length of the wall, we need to set up a proportion.
Let L = the length
W = the width
Use the first and second fractions
W = 2(2.5) = 5 in = width
Use the first and third fractions
L = 3(2.5) = 7.5 in = length
Actual Area = LW = 7.5(5) = 37.5 sq in
