The second angle will be also 89. because if the two lines are parallel,same side,and same vertex to each other so the second angle will be the same as the first.
The 15%= $8.63, If you add the $57.50+ 8.63 you get $66.13.

Step-by-step explanation:
1x10= 10
2x5= 10
Answer:
x = -2, y = 7
Step-by-step explanation:
Since it's a system of equations, we know that the they use the same variables. To use substitution to solve a system of equation, we must take one equation and solve it for a variable, then you plug the solution into that variable for the other equation:
-2x + y = 11
y = 2x + 11
-------
4x + 4y = 20
4x + 4(2x + 11) = 20
4x + 8x + 44 = 20
12x + 44 = 20
12x = -24
x = -2
Then we can plug "x" into the first equation:
-2x + y = 11
-2(-2) + y = 11
4 + y = 11
y = 7
