Answer:
x=
Step-by-step explanation:
First, we need to solve the angle inside the triangle. That would be 55+40+angle measure=180
angle measure=85°
Now that we know that, we can solve for x by setting 85-3x-18 equal to 180° because these two values form a linear pair which is 180°.
Let's use some simple algebra to solve for x:
85-3x-18=180
67-3x=180
-3x=113
x= or about -37.67
Hope this helps!! :)
Answer:
Set each factor equal to 0
4x-3 = 0
2x-1 = 0
Solve for x.
4x-3=0
4x=3
x= 3/4
Solve for x.
2x-1= 0
2x= 1
x= 1/2
Eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

Step-by-step explanation:
Sum of all angles of a triangle = 180°
So,
angle E + angle O + angle C = 180°
=> 53° + 77° + C = 180°
=> 130° + angle C = 180°
=> angle C = 180° - 130°
=> angle C = 50°
Answer:
26 child tickets
Step-by-step explanation:
4c = a to make the adult tickets equal to the child tickets multiply the child tickets by 4. then use substitution.
6.10c + 9.90(4c) = 1188.20
6.10c +39.6c = 1188.20
45.7c = 1188.20
c = 26
