Since it is given that the triangle is a right angle, and one of the other angles is 30 degrees, then we know that this triangle is a 30, 60, 90 triangle. In a 30, 60, 90 triangle, the opposite side of the shortest angle is half of the hypotenuse (which is given as 6). So knowing this, the value of y would be D. 3.
The surface area is 54 square inches
First, we are going to find the painted area of his house. We know that the total area he needs to paint is 4000 square meters, so 4000 is the area of this house. Now, to find the 62.5% of that area, we are going to multiply it by

:
Painted area=

Now, to find <span>rate, in square feet per hour, we are going to divide the painted area by the number of hours:
Rate=</span>

We can conclude that Kyler paints at a rate of
434.78 square feet per hour.
