Answer:
C. WY=77 , angle Z=110°
Step-by-step explanation:
angle X = angle Z (as shown in the figure)
So, equating the two angles,
9x+47=7x+61
or,2x=14
or,x=7
Now, angle Z=7*7+61=110°
WY=84-7=77
Answer:
<em>See below;</em>
Step-by-step explanation:
Consider the steps below;


<em>Thus, we derive such a solution;</em>
<em>m∠ 1 = 35°, m∠ 2 = 145°, m∠ 3 = 35° , m∠ 5 = 35° , m∠ 6 = 145° , m∠ 7 = 35° , m∠ 8 = 145</em>°
The Diameter is 60. The 60 represents the diameter as you may know the formula is C=d*Pi
I believe it is 6,895. I just multiplied by 197 by 35
