2. A triangular pyramid begins with these coordinates:

1 answer:

3 0

The rule for the reflection is (x,y,z) → (-x,y,z) so P' = (1, 2, 0) for example.
Then the rule is (x,y,z) → (x + 2, y + 4, z - 3) so P'' = (3, 6, -3)

Triangle ABC is a right triangle. The sides measure AB = 3 and BC = 4. Use the Pythagorean theorem to find CA. A. CA = 25 B. CA

Vesna [10]

Answer:

CA = 5

Step-by-step explanation:

Since the sides are 3 and 4, we recognize this as a 3:4:5 right triangle, with CA = 5. Using the Pythagorean theorem confirms this:

CA² = AB² +BC²

CA² = 3² +4² = 9 +16 = 25

CA = √25

CA = 5
