Answer: Yes it is.
Step-by-step explanation: So we are already told that segment AC is congruent to segment DC. They both have a right angle, as indicated by the angle symbol, and they share side-length BC.
According to the Hypotenuse-Leg Theorem, two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles. AC and DC are hypotenuses and they are congruent. And BC, the shared side, is a corresponding congruent leg. And since they are both right triangles, we then know that the HL Theorem applies.

Step-by-step explanation:
Answer:
consistent system, independent system, independent system, inconsistent system
Step-by-step explanation:
1) A system of linear equation with at least one solution is a consistent system.
2) A system of linear equation with exactly one solution that is called independent system
3) A system of linear equations with an infinite number of solution is a dependent system
4) A system of linear equations with no solution is a inconsistent system
How to solve: 20^2+5^2=x^2, then you take the square root, therefore x=20.62
