Answer:
8
Step-by-step explanation:
The sum of the internal angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5, hence
sum = 180° × 3 = 540°
Each exterior angle plus interior angle = 180°
Subtract each exterior angle from 180 for corresponding interior angle.
180 - 59 = 121, 180 - 77 = 103, 180 - 66 = 114, 180 - 62 = 118
Sum the 4 interior angles and subtract from 540 for 5 th interior angle
5 th = 540° - (121 + 103 + 114 + 118)° = 540° - 456° = 84°
The 5 th interior angle and 12x sum to 180 ( same reason as above )
Hence
12x + 84 = 180 ( subtract 84 from both sides )
12x = 96 ( divide both sides by 12 )
x = 8

Answer:
The ratio of blue balloons to the total number of balloons is 1:2.
Step-by-step explanation:
Given:
Total number of balloons = 14
Number of red balloons = 3
number of white balloons = 4
Number of the blue balloons are the rest remaining.
We need to find the the ratio of blue balloons to the total number of balloons.
Solution:
First we will find the number of blue balloons.
Now we know that;
Number of the blue balloons can be calculated by Total number of balloons minus sum of Number of red balloons and number of white balloons.
framing in equation form we get;
Number of the blue balloons = 
Now to find the ratio of blue balloons to the total number of balloons we will divide Number of the blue balloons from Total number of balloons.
framing in equation form we get;
Ratio = 
Hence the ratio of blue balloons to the total number of balloons is 1:2.

Answer:
Step-by-step explanation:
The overall change is -150 feet. 50 times 5 is 150 feet, and the mountain climber descended. Therefore, the change is -150 feet in elevation.
