Answer:

∠ZXW and ∠ZXY are right angles

Step-by-step explanation:

Two right triangles are congruent if the hypotenuse and one corresponding leg are equal in both triangles

We have indication of:

WZ = YZ
ZX is common leg

Missing information is just confirmation that both of them are right triangles

This is:

∠ZXW and ∠ZXY are right angles

Correct answer option is B

Someone pls help me.

I’m here to help.
For this question here you need to use the sine formula for the area of a triangle and figure out the area of the sector

I’ll take you through it step-by-step

Area of the arc:

We only have 68.9 degrees out of 360 and we need to use the formula for the area of a circle.
Formula of a circle = pi x radius squared

68.9/360 x pi x 86.1184= 51.78 (2dp)

Area of triangle:
As you can see we have no height so we must use the sine formula for the area of a triangle.
Formula= 1/2abSinC

You should end up with
0.5 x 9.28x 9.28 x Sin(68.9)= 40.17 (2dp)

Now since you want the area of the segment shaded, just find the difference between these two values.

51.78-40.17 = 11.61
Answer= 11.6cm squared

Hope this helped!
