Question

please tell me this solution​

Answer 1

We can find ∠E inside a triangle. ∠E should be 29° because of the interior angles.

DE is parallel to CF, therefore ∠DEF=29°.

And we can see 29° and ∠BCF is a supplementary angle of each.

Therefore ∠BCF+29°=180°. And hence ∠BCF=151°.

Therefore, the measurement is 151°.

Answer 2

Answer:

151 degress

Step-by-step explanation:

Angle DCE = (180 - (61 + 90))degrees = 29 degrees

Then angle ABC is also equal to 29 degrees (they are alternate angles)

Then angle ABC plus angle BCE add up to 180 degrees (they interior angles)

So 180 degrees - 29 degrees = 151 degrees

I am not 100% sure though
