Answer:
x = 7
Step-by-step explanation:
A, B, and C are collinear B is between A and C.
AC = AB + BC
2x + 1 = x + 4 + 2x - 10
2x + 1 = 3x - 6
2x - 3x = - 6 - 1
- x = - 7
x = 7
Answer:
Step-by-step explanation:
We know all angles in a circle or around a point is 360°
So using that we can make the equation:
the angles e and f are on a straight line so they add up to 180°
So the other side of the line will be 180 as well. Hence we can make the equation:
Answer:
this is my answer for this question
21.5
Answer:
part a is infinite Part b is number 3
Step-by-step explanation:
The length = 18.02
a^2 + b^2 = c^2
10^2 + 15^2 = c^2
100 + 225 = c^2
325=c^2
square root it and you get 18.02
