ANSWER
EXPLANATION
The given triangle has a right angle.
The side opposite to the 45° angle is 7 units.
To find angle x, we use the tangent ratio.
Recall the mnemonics TOA, which means,
To find y, we use the sine ratio, which means
Answer:
It is a proportional relation.
Step-by-step explanation:
We have given that at Time (hours) = 2, Distance (miles) = 90 and at Time (hours) = 3, Distance (miles) = 135
Therefore, the speed we get from the first two row data = miles/hr.
So, the speed is maintained through out the journey as
At t = 0, Distance = 0
At t = 2 hours, Distance = 2 × 45 = 90 miles
At t = 3 hours, Distance = 3 × 45 = 135 miles
At t = 5 hours, Distance = 5 × 45 = 225 miles
At t = 6 hours, Distance = 6 × 45 = 270 miles
Therefore, the values matches with the table.
Hence, it is a proportional relation. (Answer)
