Think of the right triangle formed by the ladder, the height of the upper end of the ladder and the distance of the bottom of the ladder from the wall.
Then x = 6 ft and the hyp is 10 ft. The trig function cos theta equals "adj side" / hyp, so, in this case,
cos theta = 6/10 = 0.6. Use the arccos x function on your calculator to find the angle x:
x = 0.927 (radians) = 53.1 degrees.
Answer:
70
Step-by-step explanation:
Complementary angles equal 90 degrees
90 - 20 = 70

Answer:
1/36 ≈ 0.028
Step-by-step explanation:
In order to get a total of 2 if you roll 2 dice, you have to roll two ones. (You can't roll a 0 and 2 because an average die does not have a zero on it)
You have a 1/6 chance to roll a 1 on the first die; and you have a 1/6 chance to roll a one on the second die.
To find the probability of this happening together you have to multiply them together.
1/6 * 1/6 = 1/36 = 0.0277778 ≈ 0.028
Answer: -225
Step-by-step explanation: since there are 9 math coins and each is -25, we need to add all of them together. -25x9=-225
