Answer:
4 units
Step-by-step explanation:
Since the two triangles are similar, their sides are proportional. To find the length of the side, you need to use the distance formula:
The coordinates you will use are (0, 0) and (-4, 0) because they correspond to points X and Y in Triangle PQR:
Then, simplify everything under the radical:
Finally, take the square root of 16:
= 4
Answer:
x = - 36
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 27 when x = 12, then
k = yx = 27 × 12 = 324, thus
y = ← is the equation of variation
When y = - 9, then
- 9 = ( multiply both sides by x )
- 9x = 324 ( divide both sides by - 9 )
x = - 36
