- [Right Triangles Only] tan∅ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use trig to find the missing side length.
<u>Step 2: Identify Variables</u>
<em>POV from the angle measure</em>
Angle = 23°
Opposite Leg = 25
Adjacent Leg = <em>x</em>
<em />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitution [tangent]: tan23° = 25/x
- Multiply <em>x</em> on both sides: xtan23° = 25
- Isolate <em>x</em>: x = 25/tan23°
- Evaluate: x = 58.8963
- Round: x ≈ 58.9
Answer:
- C. 13x = 39
- E. x + 7 = 10
- F. x – 1 = 2
Step-by-step explanation:
Putting 3 into each of the equations in place of x, you get ...
A. 3·3 = 1 . . . . false
B. 3·3 = 33 . . . . false
C. 13·3 = 39 . . . . TRUE
D. 3 +4 = 9 . . . . false
E. 3 +7 = 10 . . . . TRUE
F. 3 -1 = 2 . . . . TRUE
Applicable choices are C, E, F.
Here t is constant only x and y are variables so it reduces to
dy/ty-y^2 = 1/t^2(dx)
just solve it taking t as constant.
hope this helps
The width of the rectangle is 21.7
If area is equal to length multiplied by the width (A=LW) that would mean all we have to do to find the width of the rectangle is to divide the length (19.2) from the total area (416.64).
416.64/19.2=21.7
Hope this helped! :D
