Answer:
169 m
Step-by-step explanation:
See the image below.
Line AB represents the monument and line BC its shadow
Line DB represents the man and Line BE it shadow.
The Sun’s rays are parallel, so AC||DE.
Then ∆ABC ~ ∆DBE
AB:BC::DB:BE
x/65.8 = 1.8/0.7 Multiply both sides by 65.8
x = 65.6 × 1.8/0.7
x = 65.6 × 2.571
x = 169 m
The height of the Washington monument is 169 m.
Answer:
-6=7 NO SOLUTION
Step-by-step explanation:
First, distribute the -3 to the (k +2)
Your equation becomes, -3k-6=-3k+7
Add 3k to both sides to have the variables be on the same side
Your equation becomes, -6=7
Since that isn’t true, it’s a no solution
