True ........... I Hope this helps you answer your question.
Explanation:
Angles 1 & 2 have to equal 180. So, if ∠1 is equal to 140, ∠2 is equal to 40 because 140 + 40 = 180.
So far... we know that:
Angles 2, 9, and 11 make a triangle, a triangles "magic number" is also 180. To get 180, you must add up all of the angles. Well... we don't know ∠11 so to find it, you subtract 40 & 80 from 180. 180 - 80 - 40 = 60.
Answer:
∠2 = 40
∠11 = 60
Answer:
who gets 24 homework problems...8/24 if you simplify by dividing 8 on the num. and den. then it would be 1/3
First thing you would do is distribute the negative on the outside of the parentheses to the inside terms:
9x - 5x + 7 = 39
Now, combine like terms:
4x + 7 = 39
Subtract 7 from both sides to get variables on one side of the equal sign and constants on the other:
4x = 39 - 7
4x = 32
Divide both sides by 4 to isolate the variable x.
x = 32 / 4
x = 8
Translating this sentence into symbols: 2(x+3) = x - 5
So 2x + 6 = x - 5 and x = -11
Check: Is 2(-11+3) = -11 -5? Is -16 = -16? YES. x =-11 is right.
