Given: δabc ≅ δedf

what is the length of rounded to the nearest tenth?

a 1.1
b 3
c 3.2
d 4

I think the figure is that of a right triangle.

Its short leg = 2 - 1 = 1 unit     This is the value of y.
Its long leg = 3 - 0 = 3 units    This is the value of x.

Use the Pythagorean theorem to solve for the hypotenuse.

a² + b² = c²
1² + 3² = c²
1 + 9 = c²
10 = c²
√10 = √c²
3.16 = c

The length of the hypotenuse is C.) 3.2   rounded to the nearest tenth.

The answer is the numbers between =5 and 5

The correct answer is -4
