True or false? in order to inscribe a circle in a triangle, the circle's center must be placed at the center of the triangle

False

Step-by-step explanation:

Inscribing a circle in a triangle means that the circle touches the 3 sides of the triangle.

The center of the circle must be placed at the incenter of the triangle, you can find this point by bisecting two with a compas, the point where the lines intersect is the incenter.

This point does not necesarly coincides with the center of the triangle, so the statement is false.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
