Answer:
B' (-4, -4)
Step-by-step explanation:
When you dilate from the origin, you multiply the coordinate points by the scale factor.
B (-1, -1) × 4 = B' (-4, -4)
I hope this helps :))
Answer:
x = 6.4
Step-by-step explanation:
Set up using proportion and cross multiply to solve:
8/10 = x/8
x = 6.4
Answer:
See the attached figure which represents the problem.
As shown, AA₁ and BB₁ are the altitudes in acute △ABC.
△AA₁C is a right triangle at A₁
So, Cos x = adjacent/hypotenuse = A₁C/AC ⇒(1)
△BB₁C is a right triangle at B₁
So, Cos x = adjacent/hypotenuse = B₁C/BC ⇒(2)
From (1) and (2)
∴ A₁C/AC = B₁C/BC
using scissors method
∴ A₁C · BC = B₁C · AC
