yes that correct cause cd is 5 and ae is 7 so 7 muis 5 is 2

& what about my second answer?

- anonymous

im working on it i have to find a hypothneuse

- anonymous

okay if BD is 23 which we know that cause AC is 2 it a shape of a rectangle but when youre solving a triangle the slanted line is much shorter than BD so to find de so BD is 23 be is 2 so to find the hypothneuese you divide by 23 and 2 which is 11.5 and it say round to the nearest tenth so it be 11.5 it stay the same cause there is no hundredth.

- anonymous

so 2 is 11.5

- anonymous

ok thank you

- anonymous

no problem

Can you help me on another question

- anonymous

sure

As the second hand of the clock rotates the large gear turns 40 degrees. AE = 7 inches, and CD = 5 inches. AC, the length of the chain between the gears is 23 inches. How far does the chain around the circumference of the large gear move to the nearest tenth of an inch?

- anonymous

how do i figure this out?

- anonymous

As the chain of the large gear turns it rotates the small gears. Using the distance calculated in the previous question, calculate the angle that the small gear turns
this one also?
