Answer:
C 109
Step-by-step explanation:
First add all the known angles inside the triangle first to get 109°
Then since all angles in a triangle add to 180°
you take away 109 from 180 so
180-109 which equals 71
Then since all angles on a straight line add up to 180°
you take 71 from 180 so
180-71 = 109
so x = 109°
So if 1in = 15 mi you just multiply each number by 15 to find the number of miles
55) 30 mi
56) 22.5 mi
57) 7.5 mi
58) 48.75 mi
59) 82.5 mi
60) 108.75 mi
Answer:
Question Number 2 is 20
Question number 3 is 18x-32
Step-by-step explanation:
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12
Y=0
so, it is 6. (its my answer)
