Answer:
12.43ft
Step-by-step explanation:
From the given diagram, we simply apply the sin rule
According to the sine rule
=
y is the side y
y° = (90 - 43) = 47
z = 17
z° = 90
Input the parameters and solve;
ysin 90 = 17 sin 47
y = 12.43ft
Answer:
= 4√53 units
that is option(a)
Step-by-step explanation:
all sides of the square are of the same length
so if we get the length if this side, we can calculate its perimeter
there's this formula,
<u>side length between two points, let's say A(x, y) and B(p, q), is equal to </u>
so here we go,
the same points A and B here are
(4, 7) and (-3, 5)
therefore, side length :-
the side length comes out to be <u>√(</u><u>53</u><u>) </u>
now perimeter of a square is
4 × side length
= 4√53 units
