Question 2

Answer:

<em>The firefighter should extend the ladder at 54° of elevation.</em>

Step-by-step explanation:

<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

<em>Tangent Ratio:</em>

\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}

The woman is trapped at 91 feet up from the ground, and the firetruck is 67 feet away from the building.

The wall, the ground, and the ladder form a right triangle, where θ is the horizontal angle of the ladder.

Being the height of the woman the opposite leg and the distance where the firetruck is parked, the adjacent leg:

\displaystyle \tan\theta=\frac{91}{67}=1.3582

The angle is calculated as the inverse tangent:

\theta=arctan(1.3582)\approx 54^\circ

The firefighter should extend the ladder at 54° of elevation.

A basketball team played six games. In those​ games, the team won by 8 ​points, lost by 7 ​, won by 9 ​, won by 11 ​, lost by 3
BigorU [14]

Answer:

4

Step-by-step explanation:

From the question, we were told that a basket ball team six games and in those games, the team won by 8 points, lost by 7, won 9 , won 11 , lost by 3 and won by 6

The mean difference in games scored over the six games would be calculated as the addition of the scores divided by 6

= [8 + (-7) + 9 + 11 + (-3) + 6] / 6

= 24 / 6

= 4
