A key word to remember when doing this type of math is "SOHCAHTOA".

Sine =

Opposite over

Hypotenuse

Cosine =

Adjacent over

Hypotenuse

Tangent =

Opposite over

Adjacent

Since this is a 3, 4, 5 triangle, with the sides just multiplied by 7, the opposite of A which is 28 would be simplified to 4.

And the Hypotenuse would be simplified to 5.

So, the answer is 4 / 5!

If the velocity of a bicycle is 10 m/s how long will it take to cover a distance of 18 km<br>

Sergeeva-Olga [200]

Answer:

time taken=1800 seconds

Step-by-step explanation:

velocity=v=10m/s

distance=S=18km=18×10³m=18000m

t=?

as we know that

velocity= $\frac{distance covered}{time taken}$

velocity×time taken=distance covered

now here we have to find time

time taken= $\frac{distance covered}{velocity}$

time taken= $\frac{18000m}{10m/s}$

time taken=1800seconds
