Which of the following appear in the diagram below? Check all that apply. X Z. W O A. _XYZ B. ZYXZ C. w D. YX

iren2701 [21]

Answer:

A, C, and D.

Step-by-step explanation:

<XYZ appears in the diagram as the vertex angle Y, has two sides, YW and YX that intersect at point Y to form <XYZ.

Thus, <XYZ, line segments YW and YX all appear in the diagram given.

<YXZ does not appear because there's no vertex angle labelled X.

Match the following items.

max2010maxim [7]

Answer:

1. ∠ABD = 20°.

2. Arc AB = 140°.

3. Arc AD = 40°.

Step-by-step explanation:

Given information: ∠ADB = 70°. BD is diameter.

According to Central angle theorem, the central angle from two chosen points A and B on the circle is always twice the inscribed angle from those two points.

By Central angle theorem,

$\angle DAB=90^{\circ}$

Using angle sum of property in triangle ADB we get,

$\angle ADB+\angle DAB+\angle ABD=180^{\circ}$

$70^{\circ}+90^{\circ}+\angle ABD=180^{\circ}$

$\angle ABD=20^{\circ}$ .

Draw a line segment AO.

In triangle AOD, AO=OD, so

$\angle ODB=\angle OAD=70^{\circ}$

Using angle sum property in triangle AOD,

$\angle AOD+\angle ODA+\angle OAD=180^{\circ}$

$\angle AOD+70^{\circ}+70^{\circ}=180^{\circ}$

$\angle AOD=40^{\circ}$

Therefore length of arc AD is 40°.

The angle AOD and AOB are supplementary angles.

$\angle AOD+\angle AOB=180^{\circ}$

$40^{\circ}+\angle AOB=180^{\circ}$

$\angle AOB=140^{\circ}$

Therefore length of arc AB is 140°.

Elijah has \frac{1}{2} 2 1 bag of candy. A bag of candy weighs 55 pounds. How many pounds of candy does Elijah have?

adell [148]

Answer: 137.5 pounds

Step-by-step explanation:

Elijah has 2¹/₂ bags of candy. A single bag of candy weighs 55 pounds so to find the quantity of pounds that Elijah has, multiply 55 by the number of bags that Elijah has:

First convert bags to mixed fraction:

= 2¹/₂ = 5/2

Quantity that Elijah has:

= Number of bags * Weight per bag

= 5/2 * 55

= 137.5 pounds
