If two polygons are similar, must they also be congruent?

Mathematics
1 answer:
NISA [10]3 years ago
4 0

Answer:

I think No

Explanation:

We say two figures are similar if they have the same shape, but not necessarily the same size. <u>If they also have the same size</u>, we say they are congruent.

If -3x-8=16 what is the value of -2(x-7)
777dan777 [17]

Answer:

-3x-8=16

-3x = 16+8

-3x = 24

x = 24/-3

x = -8

= -2(x-7)

= -2(-8-7)

= 30

Hope this helps you. Do mark me as brainliest.

What is the MAD of the data set?<br><br> {10, 9, 16, 5, 10}
Oksanka [162]
First, you'd find the mean of all the numbers by doing 10+9+16+5+10 = 50/5 = 10. Second, you'd subtract all values from the mean by doing 
16 - 10 = 6
10 - 10 = 0
10 - 10 = 0
10 - 9 = 1
<span>10 - 5 = 5
Lastly, finding the mean of all 5 numbers would be, 2.4! Hope this helps!! :D</span>

Answer:

B) 11.8

Step-by-step explanation:

First write in 4 for x and 2 for y

Then multiply 1.3 times 6 (4+2) and subtract 2-6

Your expression should now be 7.8 +4

After adding these, it should be 11.8

The measurement of a central angle is 75. Find the measurement of <br> in radians
Marina CMI [18]
Circumference = 360 degrees 
<span>Circumference = 2π radians (comes from 2*pi*radius) </span>

<span>Therefore </span>
<span>360 deg. = 2*π radians </span>
<span>180 deg. = π radians </span>
<span>1 deg. = (π/180) radians </span>

<span>75 deg. = 75(π/180) radians </span>
<span>75 deg. = 75π / 180 radians </span>
<span>don't bother to try and simplify π (it is an irrational number) </span>
<span>however you can simplify 75/180 </span>
<span>both are divisible by 5 </span>
<span>75π/180 = 15π/36 </span>
<span>both are divisible by 3 </span>
<span>75 deg. = 5π/12 radians </span>

<span>We normally don't bother to go further, unless you actually need it as a decimal fraction (in which case, you will have an approximation) </span>

<span>75 deg. ≈ 1.308997 radians</span>
