Answer:
3/2 x
Step-by-step explanation:
length of a side of an equilateral triangle is x
The perimeter is
P = 3s where s is the side length
P = 3x
1/2 of the perimeter
1/2 (3x)
3/2 x
Answer:
a=2, b=-20
Step-by-step explanation:
4(2xsquared -5x+3)= 8xsquared -20x +12

<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tanθ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle θ = <em>x</em>°
Opposite Leg = 10
Hypotenuse = 21
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [tangent]: tanx° = 10/21
- Inverse trig: x° = tan⁻¹(10/21)
- Evaluate: x = 25.4633°
- Round: x ≈ 25.5°
The answer:
<span>A parallelogram is transformed according to the rule (x, y) → (x, y), this means, it is an identical application. So,for such a transformation, the value of an angle is 2Pi radians, or 360°
the answer is 360°

Answer:
5.29
Step-by-step explanation:
Pythagorean theorem is used
We will call AB x
x^2 + 6^2 = 8^2
x^2 + 36 = 64
x^2 = 28
x = 5.2915026
<u>x = 5.26</u>
