37. complementary angles always add up to 90. just subtract 57 from 90 and you get 37.
2+x=50
That is what I would do. I hope this helps!
Answer:
Option 4. x = 0
Step-by-step explanation:
we know that
The rule of the reflection of a point across the y-axis is equal to
(x,y) -----> (-x,y)
The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the y-value the same
The coordinates of triangle PQR are
P(1, 4), Q(3, 6), and R(5, 2)
Applying the rule of the reflection across the y-axis we have
P(1, 4) -----> P'(-1, 4)
Q(3, 6) ----> Q'(-3, 6)
R(5, 2)----> R'(-5, 2)
The reflection line is the y-axis
Remember that the equation of the y-axis is x=0
therefore
The equation of the reflection line is x=0
Isolate the variable on one side of the equation and everything else to the opposite side of the variable.
You can isolate the variable by undoing the operations done to the variable.
For example, if we added 5 to x (x + 5) then we would need to undo that operation. We would need to use the inverse of addition. Which is subtraction.
5x + 6 = 2(2x - 3)
5x + 6 = 4x - 6 <-- Distribute the 2
x + 6 = -6 <-- Subtract 4x from each side
x = -12 <-- Subtract 6 from each side
So, x is equal to -12.
Using it's concept, it is found that there is a:
- 0.6207 = 62.07% probability of selecting a cow.
- 0.0345 = 3.45% probability of selecting a horse.
- 0.3448 = 34.48% probability of selecting a goat.
- 0% probability of selecting a chicken.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there is a total of 18 + 1 + 10 + 0 = 29 animals, hence:
18/29 = 0.6207.
0.6207 = 62.07% probability of selecting a cow.
1/29 = 0.0345.
0.0345 = 3.45% probability of selecting a horse.
10/29 = 0.3448.
0.3448 = 34.48% probability of selecting a goat.
0/29 = 0.
0% probability of selecting a chicken.
