Answer:
x = 5
Step-by-step explanation:
Given that,
Cross multiplying both sides,
Taking like terms together,
So, the value of x is equal to 5.
About Slope - Intercept Form:
- y = mx + b
- m is the slope
- b is the y-intercept
About Standard Form:
- Ax + By = C
- A & B & C are integers
- A & B are both non-zero
- This form is good to use when wanting to find the x & y intercepts of a line
About Point - Slope Form:
- Y - Y1 = m (x -X1)
- Y1 & X1 is a point on the line
- The form allows you to identify the slope & the point on the line
Other Info:
- Remember, y comes before the x
- An ordered pair from your problem: (-3,1), -3 is x & 1 is y & x is before the y
- An ordered pair from your problem: (3,5), 3 is x & 5 is y & x is before the y
- For the graph, the vertical line is y
- For the graph, the horizontal line is x
Hope this information helps!!! :)
Answer:
c = 
km
Step-by-step explanation:
Here's the required formula to find the missing side of triangle by pythagoras theorem :
a = 20 km- b = 21 km
- c = ?
Substituting all the given values in the formula to find the third side of triangle :
Hence, the length of missing side of triangle is 29 km.
