theta: angle
C.O: opposite leg
h: hypotenuse
Substituting values we have:
sine (80) = 9 / x
Answer:
sine (80) = 9 / x
One way (among several) would be to add 700 and 300 in your head, and then add 44 and 4, also in your head, and then adding together these two sums.

Answer:

Step-by-step explanation:
According to coulombs law "the force of attraction or repulsion between two charges Q1 and Q2 in a given medium is directly proportional to the product of their charges and inversely proportional to the square of the distance separating them"

where
