Answer:

∠W = 130
∠X = 140
∠Y = 50
∠Z = 40

Step-by-step explanation:

Using 'y' and 'z' to represent angles with the corresponding names, we have ...

y + z = 90

(3b -1) +(2b +6) = 90 . . . . substitute the given expressions

5b +5 = 90 . . . . . . . . . . . . simplify

b +1 = 18 . . . . . . . . . divide by 5

b = 17 . . . . . . . . subtract 1

Then the angles are ...

y = 3b -1 = 3(17) -1 = 51 -1 = 50

z = 2b +6 = 2(17) +6 = 34 +6 = 40 . . . . note that these are complementary, as theys should be

Angles W and Y form a linear pair, so are supplementary:

W = 180 -Y = 180 -50 = 130

Angles X and Z form a linear pair, so are supplementary:

X = 180 -Z = 180 -40 = 140

Then the angle measures are ...

∠W = 130
∠X = 140
∠Y = 50
∠Z = 40

Sonbull [250]

Answer:

$\sqrt{37}$

Step-by-step explanation:

The distance d between a point (m , n ) and a line in the form

Ax + By + C = 0 , is calculated as

d = $\frac{|Am+Bn+C|}{\sqrt{A^2+B^2} }$

Here (m, n ) = (6, 2 ) and

6x - y = - 3 ( add 3 to both sides )

6x - y + 3 = 0 → A = 6, B = - 1, C = 3

d = $\frac{|6(6)+-1(2)+3|}{\sqrt{6^2+(-1)^2} }$

= $\frac{|36-2+3|}{\sqrt{36+1} }$

= $\frac{|37|}{\sqrt{37} }$

= $\frac{37}{\sqrt{37} }$ × $\frac{\sqrt{37} }{\sqrt{37} }$

= $\frac{37\sqrt{37} }{37}$ ← cancel 37 on numerator/ denominator

= $\sqrt{37}$

A cylindrical container's lateral surface is to be covered by a label. The container's diameter is 5 inches, and its height is 8

Nezavi [6.7K]

Answer:

The correct option is C. 126 in²

Step-by-step explanation:

Diameter of the container = 5 inches

⇒ radius of the container = 2.5 inches

Height of the container = 8 inches

To find how much paper is needed to create the label : We need to find the lateral surface area of the cylindrical shaped container

Lateral Surface Area of Cylinder = 2·π × radius × height

= 2 × 3.14 × 2.5 × 8

= 125.66 square inches

≈ 126 square inches

Hence, 126 square inches of paper is needed to create the label.

So, The correct option is C. 126 in²

7.7.4 Practice: Modeling: Similarity Theorems will give brainliest

Nimfa-mama [501]

Similar triangles may or may not be congruent

The height of the peak is 72 feet
The triangles are similar by AA similarity postulate

<h3>How to determine the similarity statement</h3>

First, we determine the height of the peak using the following equivalent ratios

P B : B M = T F : F M

So, we have:

$PB : 20ft= 6ft : 1ft\ 8in$

Express the units in inches

$PB : 240in= 72in: 20in$

Express as fractions

$\frac{PB}{240} = \frac{72}{20}$

Multiply both sides by 240

$PB = \frac{72 * 240}{20}$

$PB = 864$

Express as feet

$PB = 72 feet$

So, the height of the peak is 72 feet

The ratio also means that the triangles are similar by AA similarity postulate
