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° = \frac{adjacent}{hypotenuse} = \frac{25}{x}

cross- multiply

x × cos28° = 25 ( divide both sides by cos28° )

x = \frac{25}{cos28} = 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.

Solve for x.<br> 9 &lt;17 - 4.0<br> Enter your answer, as an inequality, in the box.
Rashid [163]

9 <= 17 -4x

Subtract t 17 from both sides:

-8 <= -4x

Divide both sides by-4,

2 <= x

Rewrite the inequality with the x on the left side.

Answer: x <=2
