Answer:

fifth angle = 102°

Step-by-step explanation:

A pentagon is a polygon that have 5 sides. A pentagon can be divided into 3 triangles .And the sum of angle in a triangle is 180°. Therefore the sum of interior angle in a pentagon will  be 180 × 3 = 540°. The sum of interior angles of a pentagon = 540°.

The general rule for calculating sum of the interior angles of a polygon is

sum of interior angle = (n−2) × 180°

where

n = number of sides

n = 5 since we are dealing with a  pentagon.

sum of interior  angle of a pentagon = 540°

The fifth angle can be computed when you subtract the sum of the 4 angles from 540°.

fifth angle = 540 - (88 + 118 + 132 + 100)

fifth angle = 540 - 438

fifth angle = 102°

From an 8- foot board, a carpenter sawed off one piece that was 2 3/4 feet long and another piece that was 3 1/2 feet long. How
alexdok [17]

Answer:

1 3/4 or 1.75

Step-by-step explanation:

An easy way to do this is to convert to decimals

1/4 = 0.25

2/4 = 0.5

3/4 = 0.75

Now, for the numbers for this problem.

2 3/4 would be equal to 2.75

3 1/2 would be equal to 3.5

Add those two numbers together and you get 6.25

Subtract that from 8 and you get 1.75 or 1 3/4
