Answer:
(a)
Step-by-step explanation:
using the following
The sum of the 3 angles in a triangle = 180°
The sum of the angles on a straight angle = 180°
To find x subtract the sum of the 2 given angles in the triangle from 180
x = 180 - (56 + 38) = 180 - 94 = 86 ( sum of angles in a triangle )
To find z, subtract x from 180
z = 180 - 86 = 94 ( angles on a straight angle )
To find y subtract the sum of the 2 angles from 180
y = 180 - (94 + 19) = 180 - 113 = 67
x = 86, y = 67 and z = 94
So you need to find the distance from the warehouse to the airport to the factory. The factory is 88 miles north of the warehouse.
You should notice that each block is 11 miles. 88 miles happens to be a multiple of 11. 88/11 = 8, so the factory is 8 blocks above the warehouse.
(See attachment)
Now use Pythagorean theorem. If one leg of the triangle is 88 and the other leg is 66, then to find the hypotenuse:
88² + 66² = x²
x = 110
So now you that you have the sides of the triangle, you can easily determine the answer.
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.
