What is the length of the radius, r? 8 units 10 units 12 units 16 units

10 units

Step-by-step explanation:

The complete question is:

Line segment KL is tangent to circle J at point K.

What is the length of the radius, r?

see the attached figure

we know that

KL is perpendicular to KJ ----> because KL is tangent to circle J at point K

so

Triangle KLJ is a right triangle

Applying the Pythagorean Theorem

substitute the given values

solve for r

i dont understand the question? ?

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
