Answer:
Step-by-step explanation:
We have been provided a graph of a triangle and we are asked to find the length of segment DE.
Angle bisector theorem states that if a ray bisects an angle of a triangle, then it bisects the opposite side of triangle into segments that are proportional to other two sides.
By angle bisector theorem we can set proportions of the given sides as:
Upon substituting our given values in above proportion we will get,
Upon multiplying both sides of our equation by 2 we will get,
Therefore, the length of segment DE is 4 units.
Step-by-step explanation:
area = ( base 1 + base 2 ) ÷ 2 x height
50 = ( 10 + 15) ÷2 x height
50 ÷ 12.5 = height
height = 4
Answer:
40%
Step-by-step explanation:
20 out of 50 simplifies to 2 out of 5 which is equivalent to 4 out of 10 which is also 40 out of 100 which is 40%.
