The solution to the problem is as follows:
Since given are :
s = length of arc = 35
r = 15
Use the formula:
s = r*theta
theta = s / r = 35 in / 15 in = 2.3 radians
Therefore, the angle of rotation of the blade is 2.3 radians.
I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
The perimeter of ABCDE is 38 inch.
Step-by-step explanation:
From the given figure it is notices that


It is given that both figure are similar. The corresponding sides of similar figures are proportional.
Since the figures ABCDE and HIJFG are similar,therefore the corresponding sides of both figures are proportional.
In figures ABCDE and HIJFG,




The perimeter of ABCDE is

Therefore the perimeter of ABCDE is 38 inch.
