12.2+14+14+6=46.2
of semi circle
circumference of semi circle = d
x10 = 10
semi circle so divide by 2 = 5
5 = 15.7
46.2 + 15.7 = 61.9
Question:
The image of the question is attached below.
Answer:
x = 40
Solution:
Given ΔVDG ΔVNG.
DG = 207, NQ = 138, GQ = 60, QV = x
In two triangles are similar, then the measures of the corresponding sides are in proportional to each other.
Do cross multiplication, we get
Divide by 207 on both sides of the equation, we get
⇒ x = 40
⇒ QV = 40
Hence the value of x is 40.
