I got 47.01816163 metres. When I tried to round it I got it wrong. Can someone please help me?
DerKrebs [107]

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

I need to find x can someone please help
PIT_PIT [208]

Answer:

\boxed{\boxed{\tt x=87^{\circ}}}

Step-by-step explanation:

We know that a triangle has 3 sides, A triangle's interior angles add up to 180 degrees.

Now, let's write this as an equation:

\tt x^{\circ}+37^{\circ}+56^{\circ}=180^{\circ}

The missing angle is 180° minus the sum of the other two angles.

\tt x^{\circ}=180^{\circ}-56^{\circ}-37^{\circ}

Subtract the numbers:

\tt 180^{\circ}-56^{\circ}-37^{\circ}=87^{\circ}

\tt x=87^{\circ}
