Answer: 1. False 2. False 3. False

Step-by-step explanation:

All circles are similar Figures can be proven similar if one, or more, similarity transformations can be found that map one figure onto another. Consequently, a circle is defined by only one length - the radius.

Find the measure of angle A. 71° x+49 +72

slega [8]

Answer: 66 degrees

Step-by-step explanation:

Sum of the angle measures is 180, so:

71 + x + 49 + x + 72 = 180

2x + 192 = 180

2x = -12

x = -6

Meaning the measure of angle A = -6 + 72 = 66 deg.

In the image, shape ABCD is similar to shape WXYZ. Find the measure of side ZW.

vladimir2022 [97]

Solution:

we are given that

In the image, shape ABCD is similar to shape WXYZ.

we have been asked to find the measure of side ZW.

As we know that when two shapes are similar then the ratios of their corresponding sides are equal.

So we can write

$\frac{zw}{6}= \frac{18}{24}\\
\\
ZW=6*\frac{18}{24}\\
\\
ZW=\frac{18}{4}\\
\\
ZW=4.5\\$

Hence ZW=4.5 Inches.

Answer:

Step-by-step explanation:

${ {a}^{b} }^{c} = {a}^{bc } \\ in \: this \: case \\ { ({8}^{n}) }^{3} = {8}^{3n} \\ \\ {8}^{3n} = {8}^{6 } \\ 3n = 6 \\ n = \frac{6}{3} = 2$

Explain why a + b = d. B A C swer

bixtya [17]

Answer:

Explanation below

Step-by-step explanation:

Angles in a Triangle

There are two basic relations of angles we need to recall:

Supplementary angles add up to 180°
Internal angles of a triangle add up to 180°

Note a, b, and c are the internal angles of the triangle. The angle c is what is needed to a+b to complete 180°, thus:

c = 180 - ( a + b )

Also, note c and d are supplementary angles. Again, c is what is needed to d to complete 180°, thus

c = 180 - d

From the two relations above, it follows that:

a + b = d
