Answer if one side of the triangle is 1/2 of the hypotenuse then the angle opposite to it is 30° and if the remaining side is √3/2 of the hypotenuse then the angle opposite to that side is 60° acobdarfq and 7 more users found this answer helpful heart outlined30°60°90° Right Triangles All 30°60°90° Right Triangles are formed by taking half of a Equilateral Triange, as shown in the steps below Because the original triangle is Equilateral, that means all three sides are the same length This is what variable "x" is trying to tell you All three sides are the same lengthNow take away the triangle on the right, leaving only the one on the left Now you have a 30°60°90° right triangle Use the Pythagorean theorem to calculate its altitude So the length of the altitude is Now memorize the way this right triangle looks and the lengths of the three sides
