Answer:

65.9 ft

Step-by-step explanation:

The Law of Sines tells us the relationship between an angle and the opposite side. We are given the angle opposite the given side, but we need the angle opposite the side of interest.

<h3>third angle</h3>

The sum of angles in a triangle is 180°, so the measure of the angle at the balloon is ...

angle C = 180° -75° -60° = 45°

<h3>ground distance</h3>

Then the distance between Amaya and Rochelle (c) is ...

c/sin(C) = r/sin(R)

c = r×sin(C)/sin(R) = (90 ft)×sin(45°)/sin(75°)

c ≈ 65.8846

Amaya and Rochelle are about 65.9 feet apart.

If three parallel lines are cut by a transversal and one angle is measured to be 90 degrees, what can be said of the remaining?

V125BC [204]

Answer: A. There all 90 degrees

Step-by-step explanation:

Given: Three parallel lines are cut by a transversal and one angle is measured to be 90 degrees.

We know that if two lines cut by transversal the following pairs are equal:

Vertically opposite angles.
Corresponding angles.
Alternate interior angles.
Alternate exterior angles.

If one angles measures 90°, then its supplement would be 90°.

Then by using above properties , we will get measure of all angles as 90°.

A pedestal in a craft store is in the shape

Angelina_Jolie [31]

Given:
side lengths of right triangles = 12 cm ; 16 cm ; 20 cm
lateral area = 192 cm²

lateral area of a triangular prism = perimeter * height
192 cm² = (12 cm + 16 cm + 20 cm) * height
192 cm² = 48 cm * height
192 cm² / 48 cm = height
4 cm = height

The height of the pedestal in the shape of a triangular prism is 4 cm.
