Answer:
8.5 yards
Step-by-step explanation:
The overall triangle, as shown by the line dividing its hypotenuse in 2, can be shown as 2 right triangles whose lengths and widths are both 7.5 and 4. With this in mind we can use Pythagorean theorem or...
By plugging in 7.5 and 4 into <em>a </em>and <em>b </em>respectively, we get the equation:
- (7.5)^2 + (4)^2 = c^2
Now we can square 7.5 and 4, add them together and then square root the resultant to get our final answer.
- 56.25 + 16 = x^2
- 72.25 = x^2
- √72.25 = x
- x = ±8.5
The length of a triangle cannot be negative so disregard the possible negative value for 8.5.
- x = 8.5
