Which of the following choices are the angle and side lengths of the given triangle

The correct answer is D. 30°, 60°, 90°; 1,  √3, 2

Step-by-step explanation:

Let's find out the solution to this question:

Arc cos (β) = √3/2 = 1.732/2 = 0.866

β = 30°

Let's recall that the ratio of the sides of a triangle 90 - 60 - 30 is:

1 : 2 : √3

β = 30°, α = 60°, r = 2, h = 1, k = √3

The correct answer is D. 30°, 60°, 90°; 1,  √3, 2

answer: slight chance that it will happen
