Answer:
67.5cm^2
Step-by-step explanation:
area of a triangle is 0.5xaxb
Let's call the left side of this tirangle y and downside z.
3² + 6² = y²
y² = 45
y² + z² = (3 + x)²
45 + z² = 9 + 6x + x²
x² + 6² = z²
45 + x² + 6² = 9 + 6x + x²
45 + x² + 36 = 9 + 6x + x²
45 + 36 - 9 = 6x
72 = 6x
x = 12

The scale factor is About 1.077. It is important to know how to Find scale factor to understand how much smaller is the object from the other, it helps in Construction and architecture mainly but it helps with other things too.
Answer:
y = 3x
Step-by-step explanation:
Parallel means same slope
<u>Step 1: Use point slope: (y - y1) = m(x - x1)</u>
(y - 6) = 3(x - 2)
y - 6 + 6 = 3x - 6 + 6
y = 3x
Answer: y = 3x
