Actually, when you know 2 sides and an included angle, you use the Law of Cosines. (and we don't know if theta is an included angle).
Solving for side c
c^2 = a^2 + b^2 -2ab * cos(C)
c^2 = 36 + 16 - 2*6*4 * cos(60)
c^2 = 52 -48*.5
c^2 = 28
c = 5.2915
Using the Law of Sines
side c / sin(C) = side b / sin (B)
5.2915 / sin(60) = 4 / sin (B)
sin(B) = sin(60) * 4 / 5.2915
sin(B) = 0.86603 * 4 / 5.2915
<span><span>sin(B) = 3.46412

/ 5.2915
</span>
<span><span><span>sin(B) = 0.6546571451
</span>

Angle B = 40.894 Degrees
sin (A) / side a = sin (B) / side b
sin (A) = 6 * sin (40.894) / 4
sin (A) = 6 * 0.65466 / 4
sin (A) = .98199
angle A = 79.109 Degrees
angle C = 60 Degrees
There are 4 lateral faces that are triangles. Each triangle is: A =
A =
= 176
There is one base that is a square. A = L x W
A = 16 x 16
= 256
Surface area = 256 + 4(176)
= 256 + 704
= 960
Answer: B
Forgive if I am wrong, but I think the answer is 360 feet cubed
Answer:
5.5
Step-by-step explanation:
Answer:
The answer is 10 minutes.
Step-by-step explanation:
First, convert the known amount of time to a fraction.
6/21 (min over hot dogs).
Set up a proportion.
6/21 = m/35 (m being the number of minutes)
Cross multiply.
210 = 21m
Solve for m. (divide each side by 21)
m = 10
I hope this helps! :)
