Consider a triangle ABC like the one below. Suppose that a = 47, b = 59, and A = 37" (The figure is not drawn to scale.) Solve t

Yanka [14]

Answer:

B = 49.1°

C = 93.9°

c = 77.9

Step-by-step explanation:

Given:

a = 47, b = 59, and A = 37°

Required:

B, C, and c

Solution:

✔️To find B, apply the law of sines:

$\frac{sin(A)}{a} = \frac{sin(B)}{b}$

Plug in the values

$\frac{sin(37)}{47} = \frac{sin(B)}{59}$

Cross multiply

$47*sin(B) = sin(37)*59$

Divide both sides by 47

$\frac{47*sin(B)}{47} = \frac{sin(37)*59}{47}$

$sin(B) = 0.7555$

$B = sin^{-1}(0.7555)$

$B = sin^{-1}(0.7555)$

B = 49.0690779° ≈ 49.1° (nearest tenth)

✔️C = 180° - (A + B) (sum of triangle)

C = 180° - (37° + 49.1°)

C = 93.9°

✔️To find c, apply the law of sines:

$\frac{sin(B)}{b} = \frac{sin(C)}{c}$

Plug in the values

$\frac{sin(49.1)}{59} = \frac{sin(93.9)}{c}$

Cross multiply

$c*sin(49.1) = sin(93.9)*59$

Divide both sides by sin(49.1)

$c = \frac{sin(93.9)*59}{sin(49.1)}$

c = 77.8766982

c ≈ 77.9 (nearest tenth)

-3/2x-7/2=-1/2<br> how would this be solved

blondinia [14]

Answer: x= -2

Explanation: -3/2x-7/2=-1/2

-3/2x= -1/2+7/2

-3/2x= 6/2

x=(6/2)÷(-3/2)

x=6/2*(2/-3)

x=6÷(-3)

x=-2

8. Derek was observing the change in water levels in his fish pond. The table below show the change in water levels of the fish

Alla [95]

Answer:

H. 2 3/4

Step-by-step explanation:

DATE >> WATER LEVEL CHANGE (inches)
August 25 >> -0.75
September 8 >> -1 3/ 8
September 22 >> 2.5
October 6 >> -1/2
October 20 >> 1 7/8

<u>Total change:</u>

1 7/8 - (-0.75) =
1+ 7/8 + 3/4 =
1 + 7/8 + 6/8 =
1 + 13/8 =
1+ 1 5/8 =
2 5/8

The closest answer option is H. 2 3/4

What is the volume of the box below ?5cm,8cm,10cm

Alecsey [184]

Answer: Hi!

To find the volume of a box (or cube), you multiply length times width times height.

In this case, you have all of the measurements, so all we have to do is multiply them together!

5cm * 8cm * 10cm = 400

So, the volume of this box is 400cm^3!

Hope this helps!
