Let a chord join YZ, then angle XYZ = 90° and angle XZY = 90 - 54 = 36°
angle OYZ = angle XZY = 36°

Therefore, the measure of YZ = 180 - 36 - 36 = 108°

Answer:

Step-by-step explanation:

Please refer the diagram I have attached.

Alright, lets get started.

As O is the center, OX and OY will be same because both are radius.

So, the angle OYX will also be 54 degrees.

In triangle OYZ, the angle OYZ  = 90-54=36

As OY and OZ are same because both will be radius.

Angle YZO will also be 36 degree.

the sum of all three angles will be 180, so

Angle YOZ = 180-36-36=108

Hence the measure of arc YZ will be 108.

Hope it will help :)

Answer:

b

Step-by-step explanation:

to prove if NP is tangent to MN

we could prove if NPM is a right triangle

By pythagorean theorem

a^2+b^2=c^2

where a=MN=33

b=NP=180

c=MP=MQ+QP=152+33=185

so

33^2+180^2=185^2

but

1089+32400 is not equal to 34225

33489 is different from 34225

What is the midpoint between -2-3i and 3+9i
Svetlanka [38]

Answer:

1/2 + 3i is the midpoint between -2-3i and 3+9i.

Step-by-step explanation:

Given the complex number

  • -2-3i
  • 3+9i

The formula to find the midpoint of two complex number (a + bi) and (c + di) is:

M=\frac{\left(a+c\right)}{2}+\frac{\left(b+d\right)i}{2}

M=\frac{\left(-2+3\right)}{2}+\frac{\left(-3+\left(9\right)\right)i}{2}

M=\frac{-2+3+\left(-3+9\right)i}{2}

M=\frac{1+6i}{2}

M=\frac{1}{2}+3i

Therefore, 1/2 + 3i is the midpoint between -2-3i and 3+9i.
