We have to relate the angles of the trapezoid in order to find the measure of BAD.
Given:
Then
The angles are congruent because if AD and BC are congruent, and the lines are parallel, they sides will form the same angles.
Also, as the segment AD is "cut" by two parallel lines, the angles BAD and ADC are consecutive interior angles and are, therefore, supplementary.
Then, we can write:
Now, with the value of x, we can calculate the measure of BAD as:
Answer: the measure of BAD is 74°.
15 over 16 means, fifteen sixteenths, your answer is 15
Not always it depends on what kind of problem you get. Sometimes you have get a problem that does not have multiplication so then you'd start with division instead.. Get what I'm saying lol? Maybe that helps.
160 Students. If you set it up as a proportion, you will have 12/30 is equal to x/400. If you cross multiply you get 4800=30X. Then divide 4800 by 30 and you get X=160.
