<h3>
Answer: x = 65.4</h3>
==================================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(x) = 5/12
x = arccos(5/12)
x = 65.375681647836 which is approximate
x = 65.4 after rounding to one decimal place
Make sure your calculator is in degree mode. The arccosine function is the same as the inverse cosine function (shortened to
).
Given = b = 20cm, A = 500cm2 l=?
A = l×b,
500= l×20
l= 25
<em>THE LENGTH IS 25 CM</em>
