Answer:
a≈18 cm
Step-by-step explanation:
we have given:
an angle,
the adjacent side and
we need to find:
the opposite side
we know that the definition of
tan of an angle = opp. side/ adj. side
tan 61° = a/ 10
multiply both sides by 10
10 * tan61° = a
18.04047755 = a
18 ≈ a
Answer:
3
Step-by-step explanation:
Let
x---------------> <span>smaller number
y----------------> </span><span>larger number
we know that
y-x=108---------> y=108+x
</span>product------------> x*y-------> x*(108+x)-----> 108x+x²
<span>
find the derivative and equals to zero
dx/dy=108+2x</span>-------------> 108+2x=0---------> 2x=-108--------> x=-54
<span>
then
y=108+x-------> y=108-54-----> y=54
the answer is
</span>smaller number is -54
larger number is 54<span>
</span>
