6x + 1 - (2x - 5) =
6x + 1 - 2x + 5 =
4x + 6 <==
An outside angle is equal to the sum of the two opposite inside angles.
This means 150 = x + (x+20)
Now solve for X:
150 = x + x+20
simplify:
150 = 2x+20
Subtract 20 from each side:
130 = 2x
Divide both sides by 2:
x = 130/2
x = 65
Now we have X = 65
Solve for the other angle with x in it, by replacing x with 65:
x = 20 = 65 +20 = 85
The three inside angles of a triangle need to equal 180 so now we can solve for Z:
z = 180 - 65 - 85 = 30 degrees.
X = 65, Z = 30
The answer that you will get is 19/3
Answer:
last choice
Step-by-step explanation:
If we are looking at positive integers and we take out the odd ones, the only one's that are left are the even ones.
So last choice. (Also I assume AC meant the complement of A)
Answer:
10% dicount
Step-by-step explanation:
76.50 / 85.00 = .9
The airplane cost 90% of its original value, meaning you have a 10% discount
10% of 85 = .1 x 85 = 8.50
85.00 - 8.50 = 76.50
