Answer:
![\tan A](https://tex.z-dn.net/?f=%5Ctan%20A)
Step-by-step explanation:
From the diagram, side length
is opposite to angle A and side length
is adjacent to angle A.
Recall the mnemonics SOH CAH TOA.
We use TOA, because it involves opposite and adjacent.
![\tan A=\frac{Opposite}{Adjacent}](https://tex.z-dn.net/?f=%5Ctan%20A%3D%5Cfrac%7BOpposite%7D%7BAdjacent%7D)
![\tan A=\frac{a}{c}](https://tex.z-dn.net/?f=%5Ctan%20A%3D%5Cfrac%7Ba%7D%7Bc%7D)
The correct choice is A.
Answer:
3
Step-by-step explanation:
The left side of A is 1 unit
The left side of B is 3 units
The scale factor is 3
Check:
The top of A is 3 units and the top of B is 9
3*3 = 9
twice a number: 2x
is 27 more than half the number: 1/2x
2x = 1/2x + 27
Isolate the x. Subtract 1/2x from both sides
2x (-1/2x) = 1/2x (-1/2x) + 27
2x - 1/2x = 27
1.5x = 27
Isolate the x. Divide 1.5 from both sides
1.5x/1.5 = 27/1.5
x = 27/1.5
x = 18
18 is the number
