Answer:
c = 10.29417310909429
[c = 10.29 (rounded)]
Step-by-step explanation:
In a right triangle, there is a specific method to find a missing side. The two straight edges (that make up the 90-degree corner) can be called leg a and leg b. The longer side, which is called the hypotenuse, can also be called c.
(leg / side)
The relation between these sides is that:
a² + b² = c²
This is called the Pythagorean theorem.
For your triangle, leg a is 6.6, and leg b is 7.9, and the missing side (x) will be represented as c
6.6² + 7.9² = c²
43.56 + 62.41 = c²
105.97 = c²
10.29417310909429 = c
c = 10.29417310909429
c = 10.29 (rounded)

Answer:
The length of diagonal is 4.922 feet.
Step-by-step explanation:
Let the width be = w
Let the diagonal be = d
Let the length be = l
Given is that the diagonal measures three times the width, this gives:
Also given is the length of the plywood is three feet more than the width. This is :
Now, in terms of x we get:
Width = x
Length = (x+3)
Length of Diagonal = 3x
Now applying Pythagorean Theorem
Solving this we get,
We will use quadratic formula to solve this and get the answer,
x = 3/7 +/- (12√2) / -14
x = 1.64075 or x = -0.783612(neglect this negative value)
So, x = 1.64075 feet
Now length of diagonal is 3x = 3*1.64075 = 4.922 feet
So, length of diagonal is 4.922 feet.
