Supplementary is when two angles together add up to 180°, and complimentary is when they add up to 90°.
The first angles together make 90°, so they are complimentary, and they are next to each other so they are adjacent, so it is B.
The second angles are 60°, and they ardent vertical so they are none of these. The third angles add up to 180° so they are supplementary, so it is D.
The fourth angles are a right angle, and you can see by the little square at the point. And right angles are always 90°, so all you have to do is 90-55.1, and that gives you 34.9, so x=34.9, so it is A.
The fifth angles together make a straight line, and a straight line is 180°, so 180-72=108, so x=108, so it is D.
Answer:
x = 47
Step-by-step explanation:
360 = 3x+17+2x-10+x+71
360= 6x+78
282= 6x
47 = x
Answer:
56% ≤ p ≤ 70%
Step-by-step explanation:
Given the following :
Predicted % of votes to win for candidate A= 63%
Margin of Error in prediction = ±7%
Which inequality represents the predicted possible percent of votes, x, for candidate A?
Let the interval = p
Hence,
|p - prediction| = margin of error
|p - 63%| = ±7%
Hence,
Upper boundary : p = +7% + 63% = 70%
Lower boundary : p = - 7% + 63% = 56%
Hence,
Lower boundary ≤ p ≤ upper boundary
56% ≤ p ≤ 70%
Unite rate means that there must be a number 1 in the ratio. It is usually on the right part of the ratio so i would divide 2 by 2 and 0.5 by 2. Then you would get 0.25:1
Answer:
y = -4x - 6
Step-by-step explanation:
y = -4x + b
6 = -4(-3) + b
6 = 12 + b
-6 = b
