PLZ HELP!<br><br> Complete this proof. <br> Given: a | | b <br> Prove: ΔMOP ~ ΔRON
SashulF [63]
As shown in the given figure
line a // line b ⇒ given
MR  and  NP  are transversals 
So, for ΔMOP and ΔRON , we can conclude the following
(1)  ∠1 = ∠2 ⇒⇒⇒ alternative angles are congruent
(2) ∠ MOP = ∠ RON ⇒⇒⇒ vertical angles are congruent
(3) ∠ 4 = ∠ 3 ⇒⇒⇒ alternative angles are congruent

So, from 1,2 and 3
∴  ΔMOP <span>~ </span>ΔRON  by  AAA-Rule

a 20-m ladder is leaning against the wall of a building which is 16m high.how far is the foot of the ladder to the building?​
mrs_skeptik [129]

Answer:

12 m

Step-by-step explanation:

This can be solved using the Pythagorean theorem

a^2 = b^2 + c^2

20^2= 16^2 + c^2

400= 256 + c^2

400-256= c^2

144 = c^2

c = √144

c= 12
