BEG is a triangle. ABC and DEF are parallel lines. work out the size of angle x.

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the measure of angle BEG

we know that

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

substitute the given values

step 2

Find the measure of angle HBC

we know that

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

we know that

---> by corresponding angles

substitute

step 3

Find the measure of angle EBG

we know that

substitute the given values

step 4

Find the measure of angle x

we know that

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

so

In the triangle BEG

substitute the given values

need points to ask question

step-by-step explanation:

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
