We are given with
<span>mXZ = 140∘
mXSZ = 220∘
and YX and YZ are tangents to circle A at X and Z.
According to the theorems on circles, the angles formed by the intersection of the two tangents is half the difference between of the measure of the arcs subtended by the tangents. So,
</span>∠XYZ = (220 - 140) /2 = 40∘<span />
<u>0.09</u> = <u>1 </u>
0.9 10
I hope this helps.

Answer:
b 15 - 4i sqrt(2)
Step-by-step explanation:
15 - sqrt (-32)
15 - sqrt(-1) sqrt(32)
15 - ±i sqrt(16) sqrt(2)
15 - ±4i sqrt(2)
Taking the principal square root
15 - 4i sqrt( 2)
