Answer:
supplementary means that < 1 and 50° together must be equal to an angle of 180°
so 180° - 50° = 130°
the second one its the same.. 50° + < 3 = 180°
so 180° - 50° = 130°
so you find out that < 1 = < 3
..if this m is meant like x and therefore this is an equation
m < 1 = m < 1 / ÷ < 1
m = m and that is true..
Answer:
Step-by-step explanation:
Supplementary angles add up to 180
∠1 + 50 = 180
∠1 = 180 - 50
∠1 = 130
∠3 +50 = 180 {Supplementary}
∠3 = 180 - 50
∠3 =130
⇒∠1 = ∠3 = 130
