Answer:

The answer to your question is below

Step-by-step explanation:

I numbered the squares, see the picture below

Angle 3 and the angle given are vertical angles so they measure the same

angle 3 = 137°

The sum of the angles 1, 2, 3 and 137 equals 360°, so

angle 1 + 137 + angle 3 + 137 = 360

and angle 1 and 3 are vertical angles so angle 1 = angle 3

2angle 1 = 360 - 137 -137

2 angle 1 = 86

angle 1 = 86 /2

angle 1 = 43°

angle 2 = 43°

The angle given and the angle 5 are corresponding angles, they measure the same

angle 5 = 137°

Angle 5 and 6 are vertical angles, they measure the same

angle 6 = 137°

Angle 2 and angle 7 are corresponding angles, they measure the same

angle 7 = 43°

Angle 3 and angle 6 are corresponding angles

angle 6 = 137°

Angle 4 and 7 are vertical angle, so they measure the same

angle 4 = 43°

How many 3 digit palindromes are divisible by 9?

ludmilkaskok [199]

Interesting problem.

A palindrome is a number which is identical when read/interpreted left-to-right or right-to-left. For example, 14241 is a palindrome, so is 444444.

A three digit palindrome must be made up of two distinct digits only, one for the first and last digits, and one for the middle, for example, 424, or 515, etc.

For a number to be divisible by 9, the sum of the digits must add up to a multiple of 9, such as 0, 9, 18, 27, etc.

We can now form a table of the possible 3-digit palindromes divisible by 9, starting with the first/last digits (=A), and finding the middle digit (=B). The number is therefore represented by the pattern ABA.

For example, when A=1, we have the number 1B1. For the number to be divisible by 9, B=7 so that sum=1+7+1=9, which is divisible by 9.

For each value of A (from 1 to 9) we can only find one value of B that makes the number divisible by 9. Thus we can only find nine such numbers, with A equal to 1 to 9.

Here's a list of the numbers

A B number

1 7 171

2 5 252

3 3 333

4 1 414

5 8 585

6 6 666

7 4 747

8 2 828

Find the number of faces, edges, and veritces of the solid

Nesterboy [21]

This is probably wrong, but from what I know, there are 16 vertices, 24 edges, and 10 faces. I’m not sure if this is wrong, but I did some math and some research, and this is what I got.

What is the function graphed below? O y= x + 0.5 O y= 2 x + 0.5 O y=x O y=(0.5)

olga2289 [7]

Answer:

A. y= x + 0.5

Step-by-step explanation:

We see that:

y- intercept is b = 0.5, point (0, 0.5)
Rate of change is m = 1 as each next value of y is greater by 1.

The function is:

y = mx + b
y = x + 0.5

Correct choice is A
