Finding angles with algebraic expressions
You need to take the concepts that we have learned to find the value of x5x x + 20
What do we know about these angles5x x + 20
What do we know about these angles They add up to 1805x x + 20
Set the two equations so they add up to 1805x x + 20 = Now solve for x 6x + 60 = 180 6x = 120 X = 20 5x x + 20
What do you know about these angles5x x + 70
What do you know about these angles They are equal to each other5x x + 70
Set the equations equal to each other and solve for x5x + 10 = 2x + 70 -2x 3x + 10 = 70 - 10 3x = 60 X = 20 5x x + 70
Find x 2x x+ 30
Find x 10x + 10 3x + 59
Solving Equations = 4x – 5(6x – 10) -132 = 4x – 30x = -26x = -26x 7 = x.
