In triangle ABC, angle bisector BM and altitude BD are drawn. In triangle BMC altitude MK is drawn. The angle between BM and BD is 20°. The angle between BM and MK is 50°. What is the ratio of the external angle measures, in lowest terms?

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
