(sat prep) find the value of x in each of the the following exercises:

Step-by-step explanation:

see the attached figure to better understand the problem

Remember that

The sum of the interior angles in a triangle must be equal to 180 degrees

In the triangle AEF

we have

----> given problem

step 1

Find the measure of angle AFE

we know that

-----> by corresponding angles

---> by supplementary angles (form a linear pair)

so

step 2

Find the measure of angle AEF

we know that

---> by supplementary angles (form a linear pair)

----> given problem

so

step 3

Find the value of x

Remember

we have

substitute

solve for x

rx and sx
