Answer: x= -7
Explanation: These equations together should equal 180 because it is a line. Therefore
x + 67 + x + 127 = 180
Combine like terms
2x + 194 = 180
Then
2x = -14
x= -7
This is simple you just need to think what minus or plus the variable in each equation (letter that represents an unknown number) equals what the equations do

Slope = -10
<span>pass through (2,-5)
y = mx + b
so
b = y - mx
b = -6 - (-10) (2)
b = -6 + 20
b = 14
equation
y = -10x + 14</span>
Answer:
corresponding angle are:
<1=<5
<2=<6
<7=<3
<8=<4
<u><1&<5,<2&<6,<7&<3,<8&<4are pair corresponding angle.</u>
Nah, it's not a right triangle because, the longest side can't insitude its self
