Answer:
x=-7
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
40 + x+57 + 90 =180
Combine like terms
187 +x = 180
Subtract 187 from each side
187-187 +x = 180-187
x = -7
Answer:
The answer is 19.
Step-by-step explanation:
Given that these lines are parallel, these two angles together equal 180.
6x +4 + 4x -14 = 180
-4 +14 +10
6x + 4x = 190
10x = 190
x = 19
