Answer:
None
Step-by-step explanation:
Distribute the 2 to the parentheses:
2(2x + 3) = 4x + 7
4x + 6 = 4x + 7
Subtract 4x from both sides:
6 = 7
6
7
This not true, since 6 can never be equal to 7.
This means there are no solutions
Step-by-step explanation:
x+ 172= 180-x
x+ 172= 180-x2x= 8
x+ 172= 180-x2x= 8x= 4°
180-4= 176
the angle is 4° and the measure of the other angle is 176°
