Answer:
tan20.tan35.tan45.tan55.tan70 =1
Step-by-step explanation:
tan20.tan35.tan45.tan55.tan70
=tan(90-70) . tan(90-55) . tan45 .tan55. tan70
[we know, tan(90-θ)=cotθ]
=cot70 . cot55 . tan45 .tan55. tan70
= { tan70°.cot70°} {tan55°.cot55°}.tan45°
=1 . 1 . 1 [we know, tan∅.cot∅ = 1 & tan45°=1]
=1

This question requires an attachment.
However, if you follow my explanation, you'll arrive at your answer
The area of a parallelogram is:


To solve for Height, we simply make h the subject of formula

In this question, we have that A = 54
Now, let's assume base (b) = 6.
This implies that


Or;
Assume that b = 3


<em>So, whatever the base of the parallelogram is;</em>
<em>You can easily solve for the height using the above steps</em>

Answer:
Step-by-step explanation:
You need the Law of Cosines for this, namely:
where x is the missing side.
and
so
x = 18.0 or just 18
