- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] sinθ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
sin 30°
<u>Step 2: Solve</u>
Since sin is opposite over hypotenuse, we need to find the length of the opposite leg of the angle and the length of the hypotenuse.
Given the triangle and it's values, the opposite leg to the 30° angle is 1 and the hypotenuse is 2.
Substituting it into sin, we have:
sin 30° = 1/2 = 0.5
∴ our answer is A.
Answer:
Neon is stable, hence has no charge.
Oxide (O2-) has a charge of -2
Cooper (Cu2+) has a charge of +2
Tin (Sn2+) has a charge of +2
hence overall charge = -2+2+2
<em><u>Over</u></em><em><u>all</u></em><em><u> </u></em><em><u>charge</u></em><em><u> </u></em>= +2
