Answer:
61.90
Step-by-step explanation:
12.2+14+14+6=46.2
of semi circle
circumference of semi circle =
d
x10 = 10
semi circle so divide by 2 = 5
5
= 15.7
46.2 + 15.7 = 61.9
.0625 ...........................................................................
For a 45 45 90 triangle if the legs are x length then the hyptonuse is x√2
a.
7=x
so hyptonuse=7√2 in
b.
sin(45°)=(√2)/2
c.
not sure what you need SAS for
but, area=1/2 times base times height
base=height=7
area=1/2 times 7 times 7=24.5 square inches
d. not sure, same as above?
Answer:
Step-by-step explanation:
A triangular prism is a prism that has two triangular faces and three rectangular sides.
The area of the rectangular sides is A = lbh
A = area, l = length, and h = height.
The area of the triangular faces is A = 1/2bh
A = area, b = base, and h = height.
