Answer:
(a)ΔLAW≅ ΔWKL
(b) ASA rule of Congruency
Step-by-step explanation:
It is given that AW⊥WL and WL⊥KL, also ∠AWL=∠KLW ( Each 90°) and ∠ALW=∠LWK( Alternate angles) from the figure.
From ΔLAW and ΔWKL, we have
∠AWL=∠KLW ( Each 90°)
WL=WL (Common)
∠ALW=∠LWK( Alternate angles)
Therefore, by ASA rule of congruency,
ΔLAW≅ ΔWKL.
Hence proved.
Answer:
The √40 simplified is 2√10
Step-by-step explanation:
Rewrite 40 as 2^2 (times) 10
Factor 4 out of 40
√4(10)
rewrite 4 as 2^2
√2^2(10)
Pull terms out from under the radical
2√10
