Answer:
11/15 = 73%
Step-by-step explanation:
because in total there are 15 cards and 4 of them is not green. You would want to see what is the probability of other colored carded after leaving out the green ones.
cos(x) = ³/₅
cos⁻¹[cos(x)] = cos⁻¹(³/₅)
x ≈ 53.13
sin(2x) = sin[2(53.13)]
sin(2x) = sin(106.26)
sin(2x) = 0.960001
cos(2x) = cos[2(53.13)]
cos(2x) = cos(106.26)
cos(2x) = -0.27999657
tan(2x) = tan[2(53.13)]
tan(2x) = tan(106.26)
tan(2x) = -3.428617001
Answer:
X = -14
All you have to do is type in 2(x+5)=(x-4) in to a algebra calculator and you will get -14
You cannot rely on the drawing alone to prove or disprove congruences. Instead, pull out the info about the sides and angles being congruent so we can make our decision.
The diagram shows that:
- Side AB = Side XY (sides with one tick mark)
- Side BC = Side YZ (sides with double tickmarks)
- Angle C = Angle Z (similar angle markers)
We have two pairs of congruent sides, and we also have a pair of congruent angles. We can't use SAS because the angles are not between the congruent sides. Instead we have SSA which is not a valid congruence theorem (recall that ambiguity is possible for SSA). The triangles may be congruent, or they may not be, we would need more information.
---------------
So to answer the question if they are congruent, I would say "not enough info". If you must go with a yes/no answer, then I would say "no, they are not congruent" simply because we cannot say they are congruent. Again we would need more information.

Answer: 5</h3>
Explanation:
Plug z = 9 into the second equation and solve for x.
x/z = 2/3
x/9 = 2/3
x = 9*(2/3)
x = 18/3
x = 6
This leads to
xy = 30
y = 30/x
y = 30/6
y = 5
