Answer: Yes it is.
Step-by-step explanation: So we are already told that segment AC is congruent to segment DC. They both have a right angle, as indicated by the angle symbol, and they share side-length BC.
According to the Hypotenuse-Leg Theorem, two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles. AC and DC are hypotenuses and they are congruent. And BC, the shared side, is a corresponding congruent leg. And since they are both right triangles, we then know that the HL Theorem applies.
You have the formula already, just plug in 30 for s (speed) and solve for d (distance).
Answer:
18
Step-by-step explanation:
Given
4(n - 4) + 14 ← substitute n = 5 into the expression
= 4(5 - 4) + 14
= 4(1) + 14
= 4 + 14
= 18
