What is the measure of Angle 1
2 answers:
Answer:
The measure of ∠1 is 125° .
Step-by-step explanation:
Definition of vertically opposite angles
As the two lines crosses angle opposite to each other are called vertically opposite angle.
Thus
As the line f and w crosses each other .
∠2 = 55°
As
∠1 + ∠2 = 180°
(∠1 and ∠2 are supplementary angles there add up sum is 180° .)
∠1 + 55 = 180
∠1 = 180 - 55
∠1 = 125°
Therefore the measure of ∠1 is 125° .
M<1 = 125 degrees. This is because angle 1 next to it say it is angle 3 is 55 degrees. Angle 3 and 1 are supplementary (meaning they add up to 180 degreees). SO you do 180-55 which is equal to 125 degrees.
