Answer:
x=5
Step-by-step explanation:
7x-17=18
7x=18+17
7x=35
x=35/7
x=5
Alternate interior angles are congruent. Therefore, set the two angles equal to each other and solve for x.
3x+4= 115
3x+4 -4 = 115 -4
3x = 111
x= 111/3---> 37. Therefore, x = 37.
Answer: A. 62.7
Step-by-step explanation:
Using the Pythagorean Theorem, know the distance from the top of the tower to the spot on the ground 750 feet away is 1636 feet.
Now with all lengths of the triangle we can solve for the angle giving us 62.7169723304
Now we round to the tenth as instructed and get an answer of 62.7
I am not completely positive but,
1/6 tons because 2/3 divided by 4 is 1/6 <span />
Combination Formula: (n = distinct objects, r = how many you pick) n!/(r!(n-r)!
So n = 7, r = 5
n! = 7! = 5040
R! = 5! = 120
(n-r) = 2! = 2
120*2=240
5040/240 = 21
21 combinations!
