(7+x)+x=15
I did trial and error to get x=4.
Yes it is a rational number.
Step-by-step explanation:
1. 21√n/2
2. 2/3 3√x
(3) - 5/2b 7/2
4. (10m) 6/5
Answer:
4 sqrt(3) =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 60 = x / 8
8 sin 60 = x
8 ( sqrt(3)/2) = x
4 sqrt(3) =x
