Answer:
<u>x = 36</u>
Step-by-step explanation:
180 - 126 = 54
90 + 54 + x = 180
144 + x = 180
180 - 144 = x
x = 36

√50 + √242 - √2
= √5·5·2 + √11·11·2 -√2
= 5√2 + 11√2 - √2
= 16√2 - √2
= 15√2

Let the distance of two consecutive stones are x, x+1.
In ΔBCD, we have
tan60
o
=
x
h
⇒x=
3
h
.....(i)
In ΔABC, we have
tan30
o
=
x+1
h
⇒

1
=
x+1
h
⇒

h
+1=

h ......[from equation (i)]
⇒

16,700,000,000,000,000 = 1.67 x 10^16
start at the last 0....count the number of spaces till u can get a decimal right after the first digit....thats 16 spaces. Now take ur numbers that are not 0...1.67....and multiply it by 10^16...because of the 16 spaces. I hope I am making some kind of sense...I am better at doing then explaining how to do...lol
