Answer:
x = 120°
y = 60°
Step-by-step explanation:
✔️since, lines l and m, area parallel, therefore,
x = 120° (they are corresponding angles having matching corners. Thus, corresponding angles are congruent to each other)
✔️x + y = 180° (linear pair angles)
Plug in the value of x
120 + y = 180
Subtract 120 from each side of the equation
y = 180 - 120
y = 60°
Answer:
Angle 5 = 35 degrees
Step-by-step explanation:
A straight line is equal to 180 degrees, meaning 1 + 2 + 5 = 180 degrees because they make up a straight line.
Angle 2 = 55 degrees
Angle 1 = 90 degrees (because it is a right angle)
Angle 5 = ?
Set up an equation:
90 + 55 + angle 5 = 180
145 + angle 5 = 180
Angle 5 = 35
The answer is number 2. Thirty cents
