In this question, it is given that the diagonal of the board is 18 inches long and one side of the board is 12 inches long.
Let the other side is of length b inches .
Now we use pythagorean identity, which is
Here, a = 12 and c=18
Substituting these values, we will get
And the formula of perimeter is
Substituting the values of the two legs, we will get
S= 15
3s=45
3s/3=45/3
S=15
You have to divide both sides
Answer:
No
Step-by-step explanation:
To make a triangle the angles have to add up to 180 degrees so 90+45+35=170 degrees not 180.
Answer:
Length = 10
Width = 13
Step-by-step explanation:
If the width of a rectangle is 3 units less than the length and if the area is 130 square units, the length is 10 units and the width is 13 units.
Formula: A=wl
Therefore, you have to find what two numbers multiply together in order to recieve 130 units.
A=wl=13·10=130
This states that a number divided by 3 is 21. the equation is: n/3 = 21
