The value of x in the expression for the angle of the triangle is 12.
The figure in the image is a triangle.
From the image:
Angle 1 = 5x
Angle 2 = 60 degrees
Angle 3 = 60 degrees
Note that, the sum of the interior angle of a triangle equals 180 degrees.
To determine the value of x, add the 3 angles and equate to 180 degrees.
Hence:
5x + 60 + 60 = 180
Collect and add like terms:
5x + 120 = 180
Subtract 120 from both sides:
5x + 120 - 120 = 180 - 120
5x = 180 - 120
5x = 60
x = 60/5
x = 12
Therefore, x has a value of 12.

Answer:
degrees Celsius.
Step-by-step explanation:
Let x represent number of kilometers.
We have been given that the temperature decreases by 6.8 degrees Celsius for every increase of 1 kilometer above the ground. So temperature decreased in x hours would be .
The ground temperature at Brigham Airport is 12 degrees Celsius. The temperature at an altitude of x kilometers would be .
To find temperature outside a plane flying at an altitude of 5 kilometers, we will substitute in our expression as:
Therefore, the temperature outside a plane flying at an altitude of 5 kilometers would be degrees Celsius.
