Given: EDF=ABF<br> Name the postulate or theorem you can use to prove ADE=EBA.
Phoenix [80]

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.

gogolik [260]

Answer: 1

Step-by-step explanation:

Given:

Geraldo current age = 25years.

Policy being considered for = 30years

Age at the end of the policy = 55years

What is the probability that Geraldo lives to be 55years.

Therefore

P ( A + B ) = 25 /55 + 30 / 55

= 5 / 11 + 6 / 11

= 11 / 11

= 1

If the hypotenuse is 41 inches, and one of the legs is 40 inches, what is the length of the other leg in inches?
arsen [322]
We will use the Pythagorean theorem:
c² = a² + b²
41² = 40² + b²
1681 = 1600 + b²
b² = 1681 - 1600
b² = 81
b = √ 81
b = 9 in
Answer: The length of the other leg is 9 inches.
