Answer:
3
Step-by-step explanation:
5x + 40 = 55
5x = 55 - 40
5x = 15
x = 15 / 5
x = 3
The value of x in the triangle is (a) 22
<h3>How to solve for x?</h3>
The complete question is in the attached image.
From the attached image of the triangle, we have:

Evaluate sin(45)

Solve for x

Divide
x = 22
Hence, the value of x is (a) 22

Answer:
graphhhhhh
Step-by-step explanation:
The slope is -3/4 so you up 3, left 4. or down 3, right 4.
You start at 1 on the y axis and then do this^.
Then you look at the line you have made and see which points are obvious.
You can just copy what I got on the graph below.
The beginning of the line segment starts at 5, and ends at 9.
Therefore,
5 - 9 = 4
The length of the segment is 4.
F(x)=2(x+10)=24
2(x+10)=24
divide 2
x+10=12
minus 10
x=2
