In the pully system shown in this figure, MQ = 10 in, NP = 3in and QP=24in. Find MN
1 answer:
Answer:
The correct option is a. The length of MN is 25.
Step-by-step explanation:
Given information: MQ = 10 in, NP = 3 in and QP=24 in.
If the centers of two circles of radius r₁ and r₂ are d units apart, then the length of the direct common tangent between them is
Square both sides.
Take square root both sides.
Therefore length of MN is 25 and option a is correct.
