Answer:
x = 30
Step-by-step explanation:
Supplementary angles total 180°.
5x° +x° = 180°
6x = 180
x = 180/6 = 30
The value of x is 30.
Answer:
5
Step-by-step explanation:
given that x and y are proportional, they can be expressed as y = rx, where r is the proportionality constant. Thus, we can solve for r by doing y/x in any given point.
Answer:
d
Step-by-step explanation:

Answer:
c
1,400
Step-by-step explanation:
We take the sample proportion of skunks and estimate for the entire population.
Sample:
140 skunks out of 230 + 140 + 120 = 490 animals.
140/490 = 0.28571428571
If a random sample of 5,000 animals are trapped in the city, how many skunks would be estimated to be included?
0.28571428571 out of 5000. So
0.28571428571*5000 = 1429
Close to 1400, which means that the answer is given by option C.
Answer:
95 degrees
Step-by-step explanation:
In a quadrilateral where there are two pairs of parrallel sides, the angles adjacent to each other are supplementary and add to 180 degrees. This means Angle A + Angle B = 180, Angle B + Angle C = 180, Angle C + Angle D = 180 and Angle D + Angle A = 180. If Angle A is 85 degrees then Angle B is 95 degrees. There are only two distinct angle measures within the quadrilateral. All angles for the quadrilateral are 85 or 95 degrees.
