Answer:
34
Step-by-step explanation:
The sum of the angles of a triangle is 180
26x+6 + 21x-1 +11x+1 = 180
Combine like terms
58x +6 = 180
Subtract 6 from each side
58x = 180-6
58x = 174
Divide by 58
58x/58 =174/58
x=3
We want <C
<C = 11x+1 = 11*3+1 = 33+1 = 34
When the number is odd and a multiple of 3, the number that Ethan is thinking of is -9.
<h3>How to illustrate the number?</h3>
In mathematics, a multiple is the product of any quantity and an integer. It should be noted that, for the quantities a and b, it can be said that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.
In this case, Ethan is thinking of a negative number that is lower than -4 and higher than -10 and his number is odd and a multiple of 3. The number is -9 since 9 is a multiple of 3.

For 1. If two lines are parallel, the slopes are the same.
If two lines are perpendicular, the slopes are the opposite reciprocal, or is -1.
2. The answer is 3/2. Because in a perpendicular slope of a line, it has to be opposite sign and the reciprocal.
3.It is parallel.
because first we solve 6x-3y=8
We move the 6x to the other side, making it -6x
Now we have -3y=-6x+8
We use the y=Mx+b
-3y=-6x+8
Then we divide by -3
answer: y= 2x-8/3
now compare
y=2x+3
and
y=2x-8/3
With this we know it’s parallel because it’s the same slope but different y-intercept .
