Answer:
x = 10
Step-by-step explanation:
(4x)° & (3x+10)° are corresponding angles. If both the angles will be equal , then we can say that A║B.
If the value of x will be 10 , then it will make A║B.
The triangle is drawn and is shown in the image attached with.
We get two similar triangles. Triangle ABC and Triangle ADE. Since the triangles are similar the ratio of their corresponding sides will be the same.
D and E are the midpoints of AB and BC, therefore, AD and AE are both 4 units in length. Using the property of similar triangles, we can say:
AD : DE= AB : BC
AD = 4 units
AB = 8 units
BC = 6 units
DE = unknown = x units
So,
Therefore, the length of DE will be 3 units
