Answer:
The scale factor, or linear scale factor, is the ratio of two corresponding side lengths of similar figures.
Step-by-step explanation:
Answer:
15 ft
Step-by-step explanation:
Pythagoras formula for a triangle with a 90 degree angle :
a^2 + b^2 = c^2
c is the side opposite of the 90 degree angle. exactly or situation here.
=> 9^2 + 12^2 = x^2
=> 81 + 144 = x^2 = 225
=> x = sqrt(225) = 15
Answer:
11. ∠B ∠ABC ∠CBA ∠2
17. QR = 12
Step-by-step explanation:
11. ∠B ∠ABC ∠CBA ∠2
17. Given: PS = 18 PR = 15 PQ ≅ RS
It would be good if you could draw a picture for yourself
So, RS = PS - PR
= 18 - 15 = 3
RS = PQ = 3
QR = PS - RS - PQ
= 18 - 3 - 3
= 12
