Answer:
28 m
Step-by-step explanation:
The top angle in the triangle = 90° - 62° = 28°
Using the cosine ratio in the right triangle
cos28° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{25}{x}[/tex]
cross- multiply
x × cos28° = 25 ( divide both sides by cos28° )
x = [tex]\frac{25}{cos28}[/tex] = 28.31425... ≈ 28 m
Thus the distance from the top to the crocodile is 28 m
Answer:
28.31 m to the nearest cm.
Step-by-step explanation:
Note the angle next to the crocodile measures 62 degrees ( alternate angles).
The required distance is the hypotenuse of the triangle and the height 25m is the opposite side to the angle of 62 degrees..
Therefore we have sin 62 = 25 /x where x is the distance required.
x = 25 / sin 62
= 28.31 m.
