Which two sets of angles are corresponding angles?

mojhsa [17]

Answer:

∠a and ∠d; ∠b and ∠c

Step-by-step explanation:

The two triangles as similar triangles and the scale factor is 2 : 1

The sides measuring 6 and 3 are corresponding sides

The sides measeuring 8 and 4 are ocrreposnding sides

⇒ ∠a and ∠d are corresponding angles

The sides measuring 8 and 4 are corresponding sides

The sides measeuring 4 and 2 are ocrreposnding sides

⇒ ∠b and ∠c are corresponding angles

I need help fast! Given the diagram below, find the length of CH.

ollegr [7]

Answer:19.8

Step-by-step explanation: if you look at the lines it describes the length of the area it’s on. Since there is 4 lines on right side it would be 9.9+9.9 which would give you and answer of 19.8 so CH=19.8

Step 1: Find the mean. mean = StartFraction 32 + 4 + 12 + 40 + 20 + 24 Over 6 EndFraction = 22 Step 2: Find each absolute deviat

DedPeter [7]

Answer:

(C)Stefano should have divided by 6 when finding the mean absolute deviation.

Step-by-step explanation:

Step 1: Find the mean.

$Mean = \dfrac{32 + 4 + 12 + 40 + 20 + 24}{6}=22$

Step 2: Find each absolute deviation.

10, 18, 10, 18, 2, 2

Step 3: Find the mean absolute deviation.

$M A D = \dfrac{10 + 18 + 10 + 18 + 2 + 2}{4} =\dfrac{60}{4}=15$

However, there are 6 values in the data. Stefano should have divided by 6 when finding the mean absolute deviation.

The correct mean absolute deviation is therefore:

$M A D = \dfrac{10 + 18 + 10 + 18 + 2 + 2}{6} =\dfrac{60}{6}=10$

How many sides does a regular polygon have if its interior angles A. 156 B. 162

Kruka [31]

I) 156 degrees
The exterior angle is 180-156
=24
The number of sides= $\frac{360}{24}$
The number of sides= 15 sides

ii) 162 degrees
The exterior angle= 180-162
=18
The number of sides= $\frac{360}{18}$
= 20 sides
