In the following diagram, BC is parrel to DE.
What is the measure of

x°=21°

Step-by-step explanation:

the angle where b is, is 54°, and this angle is equal to the angle that's left of 105°. The degree of line DE is 180°. Subtract 105° and 54° from 180° to get the missing angle that's on the right side of 105°. That angle would be 21°, and this angle is directly across the missing x°. So, x°=21°.

180-105-54=21 > this angle is directly across from the missing x°.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

the answer is d. (1.2, -4.7) on edgn

hope this !
