Answer:
x = 4 sqrt(5)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + x^2 = 12^2
64+ x^2 =144
Subtract 64 from each side
x^2 = 144-64
x^2 =80
Take the square root of each side
sqrt(x^2) = sqrt(80)
x = sqrt(16*5)
x = 4 sqrt(5)
Answer:
what is the question
Step-by-step explanation:
Answer:
<u>63 km</u>
Step-by-step explanation:
<u>Given</u> :
- Speed = 315 km/h
- Time = 12 minutes
<u>Solving</u> :
<u>Convert minutes into hours so that the units are </u><u>equal</u><u>, otherwise your answer will not be correct.</u>
- There are 60 minutes in an hour
- Therefore, 12 minutes is equal to :
- 12/60 hours
- 1/5 hours
- 0.2 hours
<u>Calculating distance</u>
- Distance = Speed x Time
- Distance = 315 km/h x 0.2 h
- Distance = <u>63 km</u>
