Answer:
i believe the answer is y =5
(13)^2 = (12)^2 +( y)^2
169= 144 + y^2
169-144= y^2
25= y^2
5 = y
There are 4 semicircles, each radius is 8cm, so we get the total areas of these semicircles: 4×0.5×
π
and the square area: 16²
so the total area of figure: 16²+4×0.5×
π=256+128π
Answer:
a^2 +b^2=c^2
Given vertices of the triangle are A(4,4),B(3,5) and C(−1,−1)
We know that slope of line passing through the points (x 1,y 1) and (x 2,y 2
) is given by m= x 2−x 1

⇒ line segments AB and CA are perpendicular to each other i.e; the given triangle is right angled at A(4,4).
Thus the points (4,4),(3,5) and (1,1) are the vertices of a right angled triangle.
Step-by-step explanation:
$1.60 is the answer. Just multiply 40 by .04 and you'll get 1.6.
