Answer:
x = a - 5
Step-by-step explanation:
3x - a = 2x - 5 ( subtract 2x from both sides )
x - a = = 5 ( add a to both sides )
x = a - 5
Everything = 360 degrees
40+40+60+75+11x+13 = 360
11x+228 = 360
11x = 132
x = 132:11
x = 12
Answer:
Step-by-step explanation:
Transversal or Corresponding angles
x=5
The formula to find the LSA of a cylinder is 2πrh
<span>4x - y =5
4x + 4y = -4
Change all the signs of the first equation
-4x + y = -5
Add 4x to both sides
y == 4x - 5
Substitute for y in second equation
4x + 4(4x - 5) = -4
4x + 16x - 20 = -4
20x - 20 = -4
Add 20 to both sides
20x = 16
Divide both sides by 20
x = 16/20 === 4/5
Substitute to find y
y == 4x - 5 == 4(4/5) - 5 == 16/5 - 5 = -9/5
