Answer:
m∠K = 69°
Step-by-step explanation:
"When two tangents or secants intersect outside the circle, exterior angle formed between the tangents of secants is one half the difference of major and minor arcs"
By this theorem,
m(∠K) = ![\frac{1}{2}[m(\widehat{LBJ}-m(\widehat{LJ})]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Bm%28%5Cwidehat%7BLBJ%7D-m%28%5Cwidehat%7BLJ%7D%29%5D)
Here, 
= 249°
= 360° - 249°
= 111°
m∠K = 
= 
= 69°
Therefore, measure of angle K = 69° will be the answer.
X would be square root of 10 because u would do properties
C=-2 because you would transfer to the other side making it negative. It can't be a negative so you divide -1 to 2. Making it -2.
The slope of a vertical line is undefined, D.
If you were to try to solve use something like the rise over run method, you would end up with a 0 in the denominator. Since dividing by 0 gives you an undefined result, the slope would be undefined.
Answer:
<h2>30 ft. tall</h2><h2 />
Step-by-step explanation:
ratio and proportion:
<u>20 ft. long</u> = <u> 4 ft. long</u>
x tall 6 ft. tall
4 (x) = 20 (6)
x = 120 / 4
x = 30 ft. tall
