X = 4.5 x = .5
Step-by-step explanation:
|2x - 5| = 4
The absolute value has two solutions one positive and one negative
2x-5 = 4 2x-5 = -4
Add 5 on each side
2x-5+5 = 4+5 2x-5+5 = -4+5
2x = 9 2x =1
Divide by 2
2x/2 =9/2 2x/2 = 1/2
x = 4.5 x = .5
The HL (hypotenuse leg) theorem states that any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
Step-by-step explanation:
AE is congruent to itself.
AB is congruent to DE
<ADE and <EBA are right angles, making them right triangles
Therefore ADE is congruent to EBA by the HL theorem.
