How do I find the value of a in 30=5a​

a = 30/5 = 6

Step-by-step explanation:

a = 6

Step-by-step explanation:

You need to try to get "a" alone.

So, since the equation shows a is being multiplied by 5, you need to divide it by 5 to get "a" alone.

Whatever you do to one side, you must do the same to the other side.

So basically, you divide both sides by 5 to find "a"

each side has a different length.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
