<u>Answer:</u>
16. x = 15
17. x = 5
18. x = 34.2
<u>Step-by-step explanation:</u>
We are given right angled triangles so using the Pythagoras Theorem to find the length of the unknown side for each triangle:

16. x = 15




17. x = 5





18. x = 34.2




Answer: Choice B) 128
Explanation:
We'll add up the given arc measures and then cut the result in half to get the angle formed by the intersecting chords (that subtend the arcs in question).
chord angle = (arc1+arc2)/2
x = (54+202)/2
x = 256/2
x = 128
X<_ 6
X>_ 15
