With math always you photo math get a calculator help and not a human and then click explain work
AB is proportional to XY since they are similar triangles making it 25:10 or 5:2
so then AC:XZ would be 5x:2x and 5x:6 so then its 15:6 since x is 3 basically set up proportions and so value of the big triangle to the small triangle would be at rails os 5:2
Your surface area is: S=x^2+4xh=84 square inches and h=2 inches; so you get:
x^2+(4×2)x=84
x^2+8x-84=0 qhich is a quadratic equation. Using the quadratic formula you get two results for x:
x1=-14 and x2=6
choose the second (positive)
Decimal: .32
fraction: 32/100 which, when reduced, is 8/25
We can find the unit rate for kph by dividing distance by time.
3470 / 5 = 694
The airplane on autopilot traveled 694kph.
