HL Theorem
Step-by-step explanation:
In the given picture, there are two right triangles .
Here one side of both triangles are equal.
Also they both have one side as common.
So they are congruent by HL Theorem.
HL theorem or hypotenuse leg theorem tells that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the triangles are congruent.Ответ:
Step-by-step explanation:
Length of:
First piece = x
Second piece = 4x
Third piece = 5x
Equation: 30 = 4x + 5x + x
Solving the Equation:
10x = 30
x = 3
Lengths of:
First piece = 3 inches
Second piece = 12 inches
Third piece = 15 inches
