1. m∠1 + m∠2 = 180°
2. Definition of bisector
3. m∠1 + m∠3 = 180°
4. Substitution Property of Equality
Answer:
a = -15
Step-by-step explanation:
a/-3 -6 = -1
add 6 to both sides
a/-3 = 5
now multiply -3 to both sides
a= -15
Answer:
4 minutes and at 70 meters
Step-by-step explanation:
-5=-5
-12+7 = x+3
-5 = x+3
-5-3 =x
x = -8
-12+7 = -8 +3
-5 = -5
Answer:
(P-2l)/2 =w
Step-by-step explanation:
P = 2l + 2w
Subtract 2l from each side
P -2l = 2l-2l + 2w
P-2l = 2w
Divide by 2
(P-2l) /2 = 2w/2
(P-2l)/2 =w
