We first solve to find the slope. The slope of the line is 5/3. Then we substitute that into the formula that is y-y1=m(x-x1). M represents the slope of the line and the x and y’s represent the point values. So we get 8-3=5/3(1+2). We get this solution if it asks you to figure out the slope along the way too.
If they ask you the equation when knowing only the two points you do 8-3=m(1+3)
They both mean the same thing ( it just depends on what the problem is specifically asking you about)

Answer:
<u>ST</u><u>=</u><u>6</u>
Step-by-step explanation:
Since the question said they were approximate it means that the difference between every side's length is the amount added to the smaller one to get the bigger triangle. You find the difference (which is 2,by the way (7-5 or OC-OU)) of the given side's and relate their similarities (in this case we'll add, so it's the difference plus the other side). We've been given TU as 4 so ST=TU+2, ie. 4+2=ST
Answer:
Step-by-step explanation:
A = 9
chord length c = 18
height h = 4
r = (c²+4h²)/(8h) = 12.125
Notice they are all right triangles. You will need Pythagorean theorem, which is a² + b² = c²
If you write down all the "equations" you can find, it is the following:
y² + 4² = x²
5² + y² = z²
x² + z² = 9²
Substitute them into one equation:
y² = x² - 4²
z² = 5² + (x² - 4²) <em>Notice that the y² is replaced with what you found </em><em>above</em>
x² + (5² + x² - 4²) = 9² <em>Notice that the z² is replaced with what's </em><em>above</em>
Now that it is just one line with one variable, you should be able to find value of x easily.
The answer is 6 if my calculations are correct.
