A homeowner leans a ladder against his house so that the top of the ladder makes a 31 degree angle with the house. What angle do
es the bottom of the ladder make with the ground? help! asap
1 answer:
If you put an imaginary line from the base of the ladder to the wall it would from a right angled triangle. The internal angles of a triangle all add up to 180degrees. With a right angled triangle, we know for sure one angle is going to be 90 degrees. One angle as you said is 31 degrees so you just add 31 and 90 which is equal to 121 then subtract it by that. SO:
180-(31+90)
180-121=59 degrees
or even easier
90-31= 59
180-(31+90)
180-121=59 degrees
or even easier
90-31= 59

Answer:
The most likely answer would be 282,240.
Step-by-step explanation:
I got a different value than the choices you've given me. But if 282,240; 14; and 21 are your only options, then the most likely answer would be 282,240. Any number followed by an exclamation point means that it will be multiplied by all whole numbers from 1 to that number. For example, 4! would be 1 * 2 * 3 * 4 = 24. In this problem, 7! equals 5,040; 8! equals 40,320; =
; and 9! = 362,880. You can tell by the listed numbers that the product will be extremely big despite the fraction, so the best choice to go with would be 282,240.
