Answer:

The correct option is (<u>A) 90°</u>

Step-by-step explanation:

The angles can be trisected which  constructive angle θ, an angle of measure 3θ can be trivially trisected.

So, the angle in option (A) is written as 3θ.

3θ=3(30°)

but rest options can't write as 3θ.

Hence, the correct option is (<u>A) 90°</u>

The angle of elevation from a soccer ball on the ground to the top of the goal is 34. If the goal is 8 feet tall, What is the di
damaskus [11]

Answer:

The distance from he ball to the goal is 11.85 feet (Approx) .

Step-by-step explanation:

As given

The angle of elevation from a soccer ball on the ground to the top of the goal is 34° .

If the goal is 8 feet tall.

Now by using the trigonometric identity .

tan \theta = \frac{Perpendicular}{Base}

As shown in the diagram given below

\theta = 34^{\circ}

Perpendicular = AB = 8 feet

Base = BC

Put all the values in the identity .

tan\ 34^{\circ} = \frac{AB}{BC}

tan\ 34^{\circ} = \frac{8}{BC}

tan\ 34^{\circ} = 0.675\ (Approx)

BC = \frac{8}{0.675}

BC = 11.85 feet (Approx)

Therefore the distance from he ball to the goal is 11.85 feet (Approx) .
