Answer: To determine the charge on an object, determine the number of excess protons or excess electrons. Multiply the excess by the charge of an electron or the charge of a proton - 1.6 x 10-19 C.
Step-by-step explanation:
Cosine again. Yay.
Put 36 into a fancy calculator with one of those cos() things. You get about 0.81.
So that's the ratio between x and 10.
So basically x/10 = 0.81, or 0.81 * 10 = x.
8.1 = x
16 squared = 256
14 squared = 196
256 + 196 = 452.
X ≤ 1 and x ≥ 3
Hope this helps :)
Angle C is Equal to 84 as well as angle A.
