Answer:
tan 30 = x / 15
General Formulas and Concepts:
<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tanθ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Angle θ = 30°
Opposite Leg = <em>x</em>
Adjacent Leg = 15
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [tangent]: tan 30 = x / 15
Answer:
I think is 10 because 2 negatives make a positive and 2 would make the answer -10
Answer:
f(x) = x^2 - x - 12
Step-by-step explanation:
The function is f(x) = (x + 3)(x - 4), or f(x) = x^2 - x - 12. Here, a = 1, b = -1, and c = -12.

Given equations:
P=w+2
p=7w-16
Compare both equations
7w-16=w+2
Add 16 to both sides.
7w=w+18
Subtract w from both sides.
6w=18
Divide both sides by 6.
w=3, which is the age of Winnie.
Now Peter's age=3+2=5 years
Option A is the correct method to find the age of Peter and Winnie.
Use a^2 + b^2 = c^2
the triangle must be isosceles because the two angles are the same
1.2^2 + 1.2^2 = x^2
1.44 + 1.44 = x^2
2.88 = x^2
x=6√2/5
or
x ≈1.69706
