<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] sinθ = opposite over hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Identify</u>
Angle θ = A
Opposite Leg = 27
Hypotenuse = 42
<u>Step 2: Solve for </u><em><u>A</u></em>
- Substitute [sine]: sinA = 27/42
- Simplify: sinA = 9/14
- Trig inverse: A = sin⁻¹(9/14)
- Evaluate: A = 40.0052°
- Round: A ≈ 40°
200 904/1000 written as a decimal is 200.904
So basically, these questions want you to find the variable<em> x</em>, which you can do by isolating the variable.
3) x * 1/2 = 1/3 <-- To isolate the x in this case, you want to divide both sides by 1/2, aka multiply by 2.
x = 2/3
4) x * 3 = 2 <-- To isolate x, you want to divide both sides by 3
x = 2/3
5) 1/4 * x = 1/6 <-- To isolate x, you want to divide both sides by 1/4, aka multiply by 4.
x = 4/6 = 2/3
6) 4 1/2 * x = 1 1/2 <-- First, let's make these into improper fractions
9/2 * x = 3/2 <-- To isolate x, you want to divide both sides by 9/2, or multiply both sides by 2/9
x = 6/18 = 2/3
Answer:
-21
Step-by-step explanation:
x3-3y
putting values in the equation
(-3)(3)-3(4)
-9-12
since the sign is minus - and - both are added but the answer will remain in minus
-21
