Hi!
These two angles are alternate interior angles, so they are congruent. Thus:
∠A = ∠B
6x + 5 = 4x + 45
Solve for x:
2x + 5 = 45
2x = 40
x = 20
Solve for ∠A by substituting in this value:
∠A = 6(20) + 5 = 125°
Answer:
3/20
Step-by-step explanation:
Take the miles that Maria walked and subtract the miles that Cody walked
3/4 - 6/10
Simplify 6/10 by dividing the top and bottom by2
3/4 - 3/5
Get a common denominator of 20
3/4 *5/5 = 15/20
3/5 *4/4 =12/20
15/20 - 12/20
3/20
