Let x be the unknown angle.
We know that x+50=120 because the value of an exterior angle of a triangle is equal to the sum of the other 2 interior angles.
x+50 = 120
Subtract both sides by 50
x = 70
The value of the unknown angle is 70 degrees.
Have an awesome day! :)
Answer:
The total distance he walked was 17/10 miles or 1.7 miles.
Step-by-step explanation:
Ron's walk was divided into two parts, one that goes from his grandmother's house to the store and then from the store to his house. The total distance that he walked is given by the sum of the two separate parts, so in order to calculate how far he walked we will do as follows:
Total distance = 8/10 + 9/10
Total distance = 17/10 mile = 1.7 miles
The total distance he walked was 17/10 miles or 1.7 miles.
The answer is B.1/2 since it is just decreasing by half ever time u go back down
Answer:

Answer:
A.
x + y = 28
1.68x + 2.44y = 54.64
Step-by-step explanation:
Let x = paperback books and y = hardback books
x+y =28
We know that paperbacks cost 1.68 and hardback cost 2.44
1.68x + 2.44y = 54.64
We have 2 equations and 2 unknowns
x+y =28
1.68x + 2.44y = 54.64
