Answer:
sides
14 X 22 = 308 square foot there are four of these
308 X 4 = 1232 square foot.
triangles
A= 0.5 X b X h
0.5 X 14 X 10 = 70 square foot again there are four of these 70 X 4 = 280 square foot
1232 + 280 = 1512 square foot
1512/213 = 7.09859154
8 gallons of paint will need to be purchased.
The answer is 2:1.
The centroid separates the median, or the point from the midpoint of a side of a triangle with its opposite angle, at a ratio of 2:1, meaning that one segment is 1/3 the length of the median and the other segment is 2/3 the length of the median.
Answer:
x = 35.4
Step-by-step explanation:
Sum of all interior angles in a triangle = 180°
Therefore:
(x + 2)° + (2x + 2)° + (2x - 1)° = 180°
x + 2 + 2x + 2 + 2x - 1 = 180
Collect like terms
x + 2x + 2x + 2 + 2 - 1 = 180
5x + 3 = 180
Subtract 3 from each side
5x + 3 - 3 = 180 - 3
5x = 177
Divide both sides by 5
5x/5 = 177/5
x = 35.4
