Question:

Solution:

Remember that if we have a straight line, then:

According to the above diagram, we have that:

then, we have the following equation:

$25\text{ + 80 + x = 180 }$

this is equivalent to:

$105\text{ + x = 180}$

solving for x, we get :

$x\text{ = 180 -105 = 75}$

thus, we have the following diagram:

then, we have the following equation:

$80\text{ + 75 + x = 180}$

this is equivalent to:

$155\text{ + x = 180}$

solving for x, we get:

$x\text{ = 180 -155 = 25}$

then, we can conclude that the correct answer is:

$x\text{ = 25}$
