13. To find the angle of WZY you would have to grab the angle of a straight line (180) and subtract it from the already shown angle of 105. 180 - 105 = 75. 75 is the measure of WZY
14. WZ has a measure of 24 since the parallel side is also 24 (not too sure about this one)
15. XYZ Has the same angle as its corresponding angle of 105. The angle is also 105
We can't tell from the information you've given.
With the dots at the end, you showed that there's more
to the decimal. But you didn't say how much more.
-- If the decimal EVER ends, even after a billion places,
then it's rational.
-- If it repeats, then it's rational. That .80012569923 may repeat,
or part of it, like the 9923, may repeat, or the whole thing may be
part of some larger bunch that repeats. We don't know.
Answer:
x=6/7 and y=18/7
Step-by-step explanation:
If y = 3x and 2x + 4y = 12,
then substitute the value of y with 3x
2x + 4(3x) = 12
2x+12x=12
14x=12
x=12/14=6/7
y=3x=3*(6/7)=18/7
For the first question, the choice at the bottom left corner is the answer.
For the second question, the two equations that represent the system of inequalities are y < 1- 3x and y ≥ 0.5x - 1
circumference =2πr=2× 7 22 ×28=22×8 =176 cm
Area =πr 2 = 7 22 ×28×28=88×28 =2464 cm 2
<u><em>circumference=176 cm </em></u>
<u><em>Area= 2464 cm 2</em></u>
