Answer:
x = 27
Step-by-step explanation:
∠ ABD and ∠ BDE are alternate angles and are congruent, then
∠ BDE = 72°
∠ ADB + ∠ BDE + ∠ EDF = 180° ( sum of angles on a straight line ), that is
2x + 72 + 2x = 180
4x + 72 = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27
Answer:
i think its the same thing
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
Step 1: Write out the expression
5(2x - 9) = -5
Step 2: Solve for <em>x</em>
10x - 45 = -5
10x = 40
x = 4
