Answer:
Angle, 
Step-by-step explanation:
We have, an A-frame house is 45 feet high and 32 feet wide. It is required to find the measure of the angle that the roof makes with the floor.
The attached figure shows the A frame. Let 
is the angle that the roof makes with the floor. So,
So, the angle of 70.4 degrees is the angle that the roof makes with the floor.
Answer:
you can use decimals
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Volume = Length times Width times height
Volume = 3 1/2 * 1 1/2 * 4
3 1/2 * 1 1/2 * 4 = 21
Hence, the answer is C
Answer:
B. 40 meters
Step-by-step explanation:
— Estimating
The rectangle enclosing the path has sides of length 9 m and 14 m, so its perimeter is 2(9+14) = 46 m. The distance covered will be shorter than that.
The distance from A to C is longer than the distance from D to C, so we know the distance will be longer than 2·14+9 = 37 m.
Only one answer choice fits in the range 37 < d < 46.
____
— Detailed calculation
The distance from B to C is the hypotenuse of a right triangle with sides 9 and 12. You will recognize that these side lengths are 3 times the side lengths of a 3-4-5 right triangle, so the hypotenuse distance is 3·5 = 15 meters.
The circuit length is ...
AB +BC +CD +DA = 2 + 15 + 14 + 9 = 40 . . . . meters
