Answer:
+) m∠1 = m∠2 (vertical angles theorem)
+) m∠2 and ∠3 are supplementary (because a//b)
+)m∠3 = m∠4 (alternate interior angles theorem, c//d)
=> ∠1 and ∠4 are supplementary (substitution property of equality)
Step-by-step explanation:
60=4/5x
4/5=0.8
60/0.8=75
X=75
Answer:
x=1/4y
Step-by-step explanation:
Step 1: You flip the equation
4x=y
Step 2: Divide both sides by 4
4x/4 = y/4
x=1/4y
