C.
not sure, goodluck. sorry if it’s wrong:)
what do you want me to answer?
You are looking at right angles in the problem. Right angles are 90 degrees.
So set up the problem to solve for X using:
90=4x+12
90-12=4x
78=4x
39/2 or 19.5 = x
Answer:
7/15
Step-by-step explanation:
it right i think if not srry :)
I'm assuming 43 is actually 4/3
see what number the previous term must be multiplied by to get the next term
4 *something = 12, 12*something=36
common ratio is 3
