Let's apply the Law of Cosines here. We want the measure of the angle opposite the side with length 16.
Call that angle C.
Then 16^2 = 36^2 + 28^2 - 2(36)(28)cos C.
Solving for C: cos C = 16^2 - 36^2 - 28^2
------------------------- = 0.904, and C = 0.44 rad
-2(28)(36) or C = 25.21 degrees
So each of the 2 equal angles shown has the measure 25.21 degrees.
Unfortunately, I don't know the direction we should go from this point on.
Answer: Choice B) multiply the radius by 2, then by 3.14
The formula is
C = 2*pi*r
which you can rearrange to get C = 2*r*pi, showing you multiply 2 and the radius r, then multiply by pi = 3.14 which is approximate
A similar related formula is
C = pi*d
where d is the diameter. Note that d = 2*r, so we can replace d with 2r to get the first formula back again.
the circumference is the distance or perimeter around the circle
Answer:
Step-by-step explanation:
let the sam's age be x
2x+5=3x-1
5+1=3x-2x
6=x
therefore sam's age is 6.
Answer: 54000 cube cm
Step-by-step explanation:
Let h be the height of the box kite,
Also the length of one face = 30 cm,
Hence, the total area of the kite box that is covered by the fabric
= 4 × Area of one face
= 4 × 30 × h
= 120 h
According to the question,
120 h = 7200
h = 60 cm
Hence, the height of the box = 60 cm,
The volume inside the kite = The base area of the box × Its height
= 30² × 60
= 900 × 60
= 54000 cm³
850.
68,750 = 350(75) + 50x
68, 750 = 26,250 + 50x
-26250
42,500 = 50x / 50
850 = x
