Given:
The figure of a trapezium.
To find:
The measures of missing angle .
Solution:
In the given figure .
If a transversal line intersect the two parallel lines, then the same sides interior angles are supplementary angles.
(Supplementary angles)
Similarly,
(Supplementary angles)
Therefore, and
.
Answer:
5:4
Step-by-step explanation:
If point B divides the segment AC in the ratio 2:1, then
AB=2x units and BC=x units.
If point D divides the segment AB in the ratio 3:2, then
AD=3y units and DB=2y units.
Since AD+DB=AB, then
Now,
So,
Answer:
The number of students in the school band = 70
40% of students in the school band are sixth graders.
20% of students in the school band are seventh graders.
We have to find the number of band members that are sixth graders.
The number of sixth graders in school band are:
Therefore, there are 28 band members that are sixth graders.
