Answer 1

Answer:

x= 51°

Exterior angle = 131°

Step-by-step explanation:

We know that exterior angle means the sum of 2 opposite interior angles.

So,

According to the question

$80 + x = 3x - 22$

$= > 3x - 22 = 80 + x$

$= > 3x - x = 80 + 22$

$= > 2x = 102$

$= > x = \frac{102}{2}$

$= > x = 51$

So,

x= 51°

Now,

∠exterior = 3x -22°

$= > 3(51) - 22$

$= > 153 - 22$

$= > 131$
