For this case, we must find an expression equivalent to:
By definition of power properties we have:
Rewriting the previous expression we have:
The "-" are canceled and we take into account that:
So:
According to one of the properties of powers of the same base, we must put the same base and add the exponents:

<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°
Answer:
11/3 divides by 60/11 = 660/33 = 20
Step-by-step explanation:
Mr. chang paid the least because 10% off 25 is more than 20%off 30
The rectangle i would say is a parallelogram. Since a parallelogram has sides that are parallel which explains the name: parallelogram :) :D
