Answer:
18 + 16 n
Step-by-step explanation:
does that equation equal anything??
Answer:
(x) =
Step-by-step explanation:
let y = f(x), then rearrange making x the subject
y =
x + 4 ( subtract 4 from both sides )
y - 4 =
x ( multiply both sides by 5 to clear the fraction )
5y - 20 = x
Change y back into terms of x with x =
(x) , then
(x) = 5x - 20
Answer: The area common to both triangle is 31.77 sq. cm.
Step-by-step explanation:
Since we have given that
30-60-90 triangles are placed.
So, the ratio of sides would be

Since Hypotenuse = 12 cm
So, it becomes,

So, Base would be

and Perpendicular would be

So, Area common to the both triangles would be

Hence, the area common to both triangle is 31.77 sq. cm.
