Step-by-step explanation:
∆PQR similar to ∆ JKL
JK/KL= PQ/QR
6/12=3/QR
QR=3×2= 6
therefore, tan(R) = PQ/QR = 3/6=1/2
and, tan(J) = KL/JK =12/6=2
tan(J)=4.tan(R)
option D
Can anyone help me out with this one?

Answer:
Upper deck = $38
Goal View = $63
Sidelines = $88
Step-by-step explanation:
Represent
- Sidelines with S
- Goal-view with G
- Upper-deck with U
We have that:
Required
Solve for S, G and U
Substitute 25 + G for S in the second equation
Make G the subject
Substitute 25 + U for G in the third equation
Collect Like Terms
Substitute 38 for U in
Substitute 63 for G in
