Answer:
x = 23
Step-by-step explanation:
For this figure, we know we are dealing with a 90 degree angle since there is a small square in the figure, therefore we can set up the equation...
65 + (x + 2) = 90
In this sense, the parenthesis are unnecessary.
67 + x = 90
-67 -67
x = 23
Hope this helps!

Answer:
Step-by-step explanation:
What percent of values is between the first and third quartiles
50 < 75 < 87.5 < 100 < 125 < 150 < 175 < 200 < 212.5 < 225 < 250
Then we have 5 values between the first and third quartiles which are :
100, 125, 150, 175, 200
Therefore,
The percent of values between the first and third quartiles is :

- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
Angle = 37°
Adjacent Leg = <em>x</em>
Hypotenuse = 10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [Cosine]: cos37° = x/10
- Isolate <em>x</em>: 10cos37° = x
- Rewrite: x = 10cos37°
- Evaluate: x = 7.98636
- Round: x ≈ 8
