First you have to find the angle that’s missing:

60+63+x=180
123+x=180
x=57

Now to find the missing exterior angle you do this:

x+57=180
x=123

Angle 1 would be 123 degrees.

how so you solve 5x+27=9(x+3)-4x and is this a conditional equation, an identity, or an inconsistent equation
Vikentia [17]

To solve this, follow these steps:

5x + 27 = 9 (x+3) - 4x

Distribute the 9 within the parenthesis:

5x + 27 = 9x + 27 - 4x

Then combine like terms:

5x + 27 = 5x + 27

These two then cancel each other out completely.

This is an identity because an identity in math is when both equations equal each other, which is shown above.

Hope this helps!
