Yes, J can be determined if H=54. The interior angles of a triangle always add up to 180. Since we know H=54 and J and I are equal.
J+I+H=180
J+I+54=180
J+I= 126
Because J&I are equal you can just divide 126 by 2
J=126/2
J= 63
Answer: true
Step-by-step explanation:
Answer:
Mile = length
Cup = Volume
Pound= Mass
Centimeter = length
Liter = volume
Gram = mass
pint = volume
yard=length
kilogram=mass
teaspoon=volume
millimeter=length
Step-by-step explanation:
D= distance
t= time
s= speed
FORMULA
Distance= speed * time
STEP 1:
Find total distance
Jim's D + John's D= 3 miles
STEP 2:
Distance= (Jim's speed * time) + (John's speed * time)
D= 4t + 5t
3 miles= 9t
divide both sides by 9
3/9= t
reduce by 3
1/3 hour= t
STEP 3:
1 hour= 60 minutes
=1/3 * 60
=(60/3)
= 20 minutes
ANSWER: They will travel 20 minutes before they meet.
