4x-9
work shown:
4x+(-7+7-9)
4x+(0-9)
final answer: 4x-9
You're going to have to set up a proportion. So it'd be 5:18=x:12 or if in fraction form, 5/18=x/12. Then you cross multiply. Where you get 5*12=18x. Then isolate the variable, (60/18) and you get 3.33 cm.
Answer:
ΔPTS≅ΔRTA by AAS axiom of congruency
Step-by-step explanation:
Consider ΔPQA and ΔRQS
∠PQA=∠RQS (Vertically Opposite Angles)
∠QAP=∠QSR (Complementary of two equal angles, ∠RAT and∠PST)
Due to angle sum property of a triangle, we come to the conclusion that
∠APQ=∠SRQ
Consider ΔPTS and ΔRTA
TA=TS (Given)
∠RAT=∠PST(Given)
∠APQ=∠SRQ (Proved above)
Therefore, ΔPTS≅ΔRTA by AAS axiom of congruency.
square both sides
2y = 64
∴ y = 64/2 = 32
The answer is option D. y = 32
You need to do length•width•height.
