Correct Answer
A. DExplanation
In a 30-60-90 triangle, the sides are in the ratio of 1:√3:2. Since side D is the longest side, it corresponds to the hypotenuse, which is twice the length of the shortest side. Therefore, side D is twice the length of side A.Rate this question:

You have created a house with a deck of cards and the roof is an isosceles right triangle. The cards are 4 inches long (the sides of your roof). What is the width of your roof (the hypotenuse of the triangle) approximately?
-
2.9 inches
-
5.6 inches
-
6.8 inches
-
8 inches

Correct Answer
A. 5.6 inchesExplanation
The width of the roof, which is the hypotenuse of the isosceles right triangle, can be found using the Pythagorean theorem. The theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the other two sides are both 4 inches long. By substituting these values into the equation, we can solve for the hypotenuse. The approximate width of the roof, therefore, is 5.6 inches.Rate this question:

Find the altitude (the height) of an equilateral triangle that has sides equal to 12 units.
-
A
-
B
-
C
-
D
-
E
Correct Answer
A. CExplanation
To find the altitude of an equilateral triangle, we can use the formula h = (√3/2) * s, where h is the height and s is the length of the side. In this case, the length of the side is given as 12 units. Plugging this value into the formula, we get h = (√3/2) * 12. Simplifying further, h = (√3/2) * 12 = (√3) * 6 = 6√3 units. Therefore, the altitude of the equilateral triangle is 6√3 units.Rate this question:
