Answer: 12/5
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
Its equal to something multiplied by 0 so it is 0
- the formula that represents the equation point- slope is the following y-y1 = m(x-x1) where the point is given (-8,-3) and the slope is -1/9
- then you mus substitute the values in the equation y-(-3) = -1/9[(x-(-8)] , resolving it y+3= -1/9 ( x+8) , y+3 = -1/9x+9/8, y = -1/9x +9/8-3, y = -1/9x-15/8
of this form the equation that represent the form point-slope is
- y+3= -1/9 ( x+8)
Answer:
Step-by-step explanation:
21/29 = 20/b
b = 20*29/21 = 580/21
a^2 + 20^2 = (580/21)^2
a = 400/21
What would you need to know to find an unknown length?
For this case you need to know three measurements.
Two measures of the triangle that is similar and a measure of the original triangle.
Thus, the fourth measure is what will be the unknown side and is the one that we must find.
How would you find that unknown length?
Let:
a, b, c: known sides
x: unknown side
By similarity of triangles we have:
x / a = b / c
From here, we clear the value of the unknown side
