Given: mKP=2mIP, mIVK =120°
Find: m∠KJL.

Step-by-step explanation:

Givens

Notice that

, by definition sum of arcs.

Replacing given values, we have

Which means

Notice that arc KP is the subtended arc by angle KJL.

We know that the angle formed by a tangen and a secant is equal to one-half of the difference of the intercepted arcs.

Therefore, the measure of angle KJL is 40°.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
