1. You are standing on top of a ridge using a clinometer trying to figure out how far your dog has wandered off in
olga_2 [115]

<u>Given:</u>

It is given that the ridge is 360 inches tall.

<u>Assumptions:</u>

Assume you are 170.1 cm tall which equals 67 inches tall, the height from your eye to the floor is 360+67 = 427 inches.

The distance from your eye level to the bottom of the ridge is 427 inches.

Assume the angle A is 60°.

<u>To find the distance from you to your dog.</u>

<u>Solution:</u>

A right-angled triangle can be formed where the angle is 60°, the distance between you and the dog is the hypotenuse of the triangle and your height from the floor is the adjacent side of the triangle.

Assume the hypotenuse of the triangle measures x inches.

To determine the length of the hypotenuse, we determine the cos of the angle.

cos \theta = \frac{adjacent side}{hypotenuse} .

cos A = \frac{427}{x} , x = \frac{427}{cos60} , cos60=0.5.

x=\frac{427}{0.5} = 854.

So if the ridge is 360 inches tall and you are 67 inches tall and the angle A is 60°, the distance between your dog and you is 854 inches.

Can someone help me with this ?
navik [9.2K]

Answer:

SSS --> SAS --> AAS --> SAS --> HL --> SSS --> ASA --> AAS --> HL --> SAS --> HL

Step-by-step explanation:

To do this problem, look at the angles that are marked congruent as well as the sides. Then look at the order that the angles and sides are placed. If it is SSS, then that means three sides are marked congruent. SAS means the order of the side and angles would be side then angles then another side. AAS means angle then angle then side. HL is when you have a right triangle and one of the legs are congruent as well as the hypotenuse. ASA means an angle then side then another angle.

What is 2/15 closest to 0, 1/2, 2
Brums [2.3K]
0 < 2/15 < 1/2 < 2

Each number is decimal form:
0 = 0.00
2/15 = 0.13(repeating 3)
1/2 = 0.50
2 = 2.00

How far from each number closet to 2/15:
0.13 - 0 = 0.13
0.50 - 0.13 = 0.37


2/15 is closer to 0.
