Since the perimeter is 45 each side is 7.5 (45 divided by number of sides).
Now the picture already divided the hexagon into one triangle, and you can make another triangle in the bottom left. You can isolate the middle part into a big rectangle and the right part into two triangles.
Area of rectangle: length * width
Area of triangle: (1/2) * base * height
Answer:
m=45 degrees
n=15 degrees
Step-by-step explanation:
m=45 degrees because other 2 angles in it's triangle =90+45=135 degrees
180 degrees in any triangle so m=180-135=45 degrees.
m+n=60 degrees so n=60-45=15 degrees
780? It’s been awhile since I’ve done area
Answer:
40% decrease
Step-by-step explanation:
The decrease in area is 20-12 = 8 square feet. As a percentage of the original area, that is ...
8/20 = 40/100 = 40% . . . . decrease in area
Answer:
It will take 13 years to Ishaan age will be 5 times William age.
Step-by-step explanation:
Given : Ishaan is 72 years old and William is 4 years old.
To find : How many years will it take until Ishaan is only 5 times as old as William?
Solution :
Let x be years since today.
According to question,
Ishaan's age is I=72+x
William's age is W=4+x
Now, We want the time for Ishaan age will be 5 times William's age:
i.e. 
It will take 13 years to Ishaan age will be 5 times William age.
By this time William will be 17 years old and Ishaan will be 85 years old.
