Answer: X = 1/2(y)

Z= 3/4(x)

But x= 1/2(y)

So z = 3/4 * 1/2(y)

Z = 3/8(y)

Total= 1/2(y) +3/8(y) + 1/8(y)

2.<br> A line goes through the points (0, 10) and (-1, 1).<br> 2a<br> What is the slope of the line?

sashaice [31]

Answer:

9

Step-by-step explanation:

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

= ( 1 -10)/(-1 -0)

= -9/-1

= 9

The measure of arc XZ is 32°.

adoni [48]

Given:

Measure of arc XZ = 32°

To find:

The measure of XYZ

Solution:

The measure of inscribed angle is half of the measure of the intercepted arc.

$$\Rightarrow m\angle XYZ = \frac{1}{2}m(ar XZ)$

$$\Rightarrow 32^\circ = \frac{1}{2}m(ar XZ)$

Multiply by 2 on both sides.

$$\Rightarrow 2\times 32^\circ =2\times \frac{1}{2}m(ar XZ)$

$$\Rightarrow 64^\circ =m(ar XZ)$

The measure of angle XYZ is 64°.
