You are standing 30 meters from a hot air balloon that is preparing to take

Mathematics

Lerok [7]3 years ago

Answer:

The distance to the top of the balloon is approximately 33.977 meters

Step-by-step explanation:

The (horizontal) distance from the hot air balloon from the observer, <em>l</em> = 30 m

The angle of elevation to the top of the balloon, θ = 28°

With the balloon standing upright, the distance to the top of the balloon, <em>d</em>, the height of the balloon, <em>h</em> and the horizontal distance to the balloon, <em>l</em>, form a right triangle, where;

d = The hypotenuse side

l = The leg adjacent to the reference (given) angle,

h = The leg opposite to the given angle, θ

By trigonometric ratios, we have;

cos\angle X = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}

From which we get;

cos\angle \theta = \dfrac{l}{d}

cos(28^{\circ})  = \dfrac{30 \ m}{d}

d = \dfrac{30 \ m}{cos(28^{\circ}) } \approx 33.977 \, m

The distance to the top of the balloon, <em>d </em>≈ 33.977 m

given:

she had: $35.13

+ her mom gave her: $7.50

+ she was paid $10.35

- add all of these up for total.

35.13 + 7.50 + 10.35

= $52.98

<em>look back at the answer i posted before for explanations. the answer for this would be 4/14, which is simplified to 2/7.</em>

Answer:

  • D. They are similar by the definition of similarity in terms of a dilation.

Step-by-step explanation:

<em>Refer to attached</em>

The points are plotted and connected to make triangles

As per the diagram, the triangles are similar, each side of ABC is reduced twice to make the corresponding sides of DEF, so the scale factor is 1/2.

<u>Correct choice is D</u>

  • They are similar by the definition of similarity in terms of a dilation.

Find sin theta if theta is an angle in standard position and the point with coordinates (3, -4) lies on the terminal side of an
alisha [4.7K]

Answer:

\sin \theta=-\frac{4}{5}

Step-by-step explanation:

Given:

Angle is in standard position which means the starting ray is at the origin. The terminal side has coordinates (3, -4).

So, the 'x' value is 3 and 'y' value id -4.

Using Pythagoras Theorem, we find the hypotenuse.

Hypotenuse = \sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5

Now, using the sine ratio for the angle, we have

\sin \theta=\frac{Opposite}{Hypotenuse}\\\sin \theta=\frac{-4}{5}\\\sin \theta=-\frac{4}{5}

Therefore, the value of \sin \theta is -\frac{4}{5}.

The value is negative as the point (3, -4) lies in the fourth quadrant and sine ratio is negative in the fourth quadrant,
