Answer: D: 17.3
Step-by-step explanation:
I believe its D because the house and the ground is a 90 degree angle, and at 60 degree angle is a 20 foot ladder. alright then 90 plus 60 = 150 degrees.
then add the twenty foot ladder with each choice for the answer:
A: 20 + 6.1 = 26.1
B: 20 + 10.0 = 30
C: 20 + 14.1 = 34.1
D: 20 + 17.3 = 37.3
The answer would be D because it is the closer number to 150. Because it says " which is the closest height up the house the ladder reaches?" The answer is D the closest number. I HOPE THIS HELPS YOU! =D
The sum of ext. angles on any convex polygon is always 360 degrees
The first set of plots do not line up.
The area here is 2 triangles and 3 rectangularso the total area is the sum of all areas area of triangle = 0.5 * base * height = 0.5 * 4 * 3 = 6 ft^2 the area of the rectangular 1 = 5 * 7 = 35 ft^2 the area of rectangular 2 = 4 * 7 = 28 ft^2 the area of rectangular 3 = 3 * 7 = 21 ft^2 so the total surface area = 2(6) + 35 + 28 + 21 = 96 ft^2
