Which side lengths form a right triangle? Choose all answers that apply: Choose all answers that apply: (Choice A) A 3, 6, \sqrt

dlinn [17]

Answer:

A, B and C

Step-by-step explanation:

Given any three side lengths of a right triangle, the longest side is the hypotenuse.

The side lengths of a right triangle must satisfy the Pythagorean Theorem.

Pythagorean Theorem: $Hypotenuse^2=Opposite^2+Adjacent^2$

Option A: $3, 6, \sqrt{45}$

$(\sqrt{45})^2=3^2+6^2\\45=36+9\\45=45$

True

Option B: 2.5, 6, 6.5

$6.5^2=6^2+2.5^2\\42.25=36+6.25\\42.25=42.25 (TRUE)$

Option C: $4, 8, \sqrt{80}$

$4, 8, \sqrt{80}\\( \sqrt{80})^2=4^2+8^2\\80=16+64\\80=80 (TRUE)$

Since all are true, the side lengths in Options A, B and C forms a right triangle,

What is the probability of the spinner landing on 2? A spinner is split into 4 equal parts labeled 1, 2, 3, and 4. StartFraction

liubo4ka [24]

Answer:

The probability of the spinner landing on 2 is one fourth.

Step-by-step explanation:

The spinner is split into 4 equal parts labeled 1, 2, 3, 4

The probability of the spinner landing on 2 is given as:

(Possibility of it landing on 2) ÷ (Total possible outcome)

The total possible outcome is 4, because the spinner could land on 1, or 2, or 3, or 4.

It can only land on 2 once, so the possibility of it landing on 2 is 1.

Probability = 1/4
