Answer:
a. 
Step-by-step explanation:
<em>hey there,</em>

< There are 8 marks between 1 in. and 2 in. and here we can see that the distance of the line goes only up to the first mark.
Imagine this like a pizza that's divided into 8, but you only took 1 slice. That means you took only
of the pizza. It is the same here on the ruler.
It's not only 1/8 though because we also have to add in the first inch. After that inch, we also have 1/8 of an inch. So
in. would be your final answer. >

Answer:
A number decreased by 8 is less than 23.
<span>Let the larger number be x.
</span><span>A number, y, is equal to the difference of a larger number and 3.
y = x - 3
x - y = 3
</span>The same number is one-third of the sum of the large number and 9.
y = (1/3)(x + 9)
3y = x + 9
x - 3y = -9
The equations are:
x - y = 3
x - 3y = -9
Since it’s equilateral and all triangles add up to 180 degrees
3(3a-9)=180
3a-9=60
3a=51
a=17
So the value of A is 17 degrees
