Can some one explain how to do this?

Mathematics
1 answer:
Delvig [45]3 years ago

Answer:

see explanation

Step-by-step explanation:

Using the tangent and sine ratios in the right triangle EFG

tan60° = \frac{opposite}{adjacent} = \frac{FG}{EG} = \frac{28}{EG} ( multiply both sides by EG )

EG × tan60° = 28 ( divide both sides by tan60° )

EG = \frac{28}{tan60} ≈ 16.2 in ( to the nearest tenth )

--------------------------------------------------------------

sin60° = \frac{opposite}{hypotenuse} = \frac{FG}{EF} = \frac{28}{EF} ( multiply both sides by EF )

EF × sin60° = 28 ( divide both sides by sin60° )

EF = \frac{28}{sin60} ≈ 32.3 in ( to the nearest tenth )

The length of a bridge is 140 m. The length of each of Robert's paces is 55 cm.
Sindrei [870]

Answer:

255 steps

Step-by-step explanation:

They give us the length of the bridge and the length of each step of Robert, therefore we must divide these values to find the number of steps necessary, but first we must pass the distance of the bridge to centimeters:

140m * 100cm / 1m = 14000

Therefore the bridge would have a length of 14000 centimeters, we divide:

14000/55 = 254.54

Which means that Robert take at least 255 steps to fully walk the bridge.
