Sum of exterior angle of a polygon is 360
90 + 10x + 5x + 45 = 360
135 + 15x = 360
15x = 360 - 135 = 225
x = 225/15 = 15
Largest exterior angles = 10x = 10(15) = 150 degrees.
Answer:
345 sq. ft
Step-by-step explanation:
You know that the area is the length times the width. Simply plug in values to your equation:
A = l * w
A = 23 * 15
A = 345
The area is 345 square feet.
Answer:
x=52
Step-by-step explanation:
160=4+3x
Subtract 4 from both sides
156=3x
Divide 3 from both sides
x=52
Let the original number be ‘x’
Then half of that number= 1/2x or simply x/2
Similarly one fifth of that number = x/5
According to the question
x+x/2+x/5=51
Taking LCM
10x/10+2x/10+5x/10=51
Multiplying 10 throughout
10x+2x+5x=510
17x=510
x=510/17
Therefore x=30
