For this case, we must find the triangle whose value of x is given by 17.
In all three cases, the value of the variable "x" is given by:
Triangle 1:
Triangle 2:
Triangle 3:
Thus, the triangle whose value of x is 17 is triangle 2.
Answer:
Option b
The actual wingspan of fly is 5.5cm
Step-by-step explanation:
Given,
Scale of drawing;
4mm = 1cm
Ratio of mm to cm = 4:1
Wingspan of fly in drawing = 22mm
Let,
x be the actual wingspan.
Ratio of mm to cm = 22:x
Using proportion;
Ratio of mm to cm :: Ratio of mm to cm
Product of extreme = Product of mean
Dividing both sides by 4
The actual wingspan of fly is 5.5cm
