Answer:

60 °

Step-by-step explanation:

Applying the law of sine we have the following:

160 / Sin B = 80 / Sin 30 °

We solve for B and we have:

160 / Sin B = 80 / 0.5

160 / Sin B = 160

Without B = 160/160

B = Arc Sin (1)

B = 90 °

Now to calculate the other angle (true

 course) would be:

A = 180 ° - (B + C)

A = 180 ° - (90 ° + 30 °)

A = 60 °

That is to say that true course is 60 °

12. The base of a pyramid is a
maks197457 [2]

Answer:

35 cubic inches

Step-by-step explanation:

The volume of a pyramid is \frac{1}{3} bh, where b = base and h = height. To find the area of the base, we multiply 3 by 5 and then divided by 2.

  • 3 × 5 = 15
  • 15 ÷ 2 = 7.5

Next, we multiply 7.5 by 14.

  • 7.5 × 14
  • 105

Lastly, we divide by 3.

  • 105 ÷ 3
  • 35

Therefore, the answer is 35 cubic inches.

If the third term in a geometric sequence is 20, and the fifth term in the
Gwar [14]

Answer: A) 1/2

Step-by-step explanation:

In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

If the third term is 20, it means that

T3 = 20 = ar^(3 - 1)

20 = ar²- - - - - - - - - - 1

If the third term is 20, it means that

T5 = 5 = ar^(5 - 1)

5 = ar⁴- - - - - - - - - - 2

Dividing equation 2 by equation 1, it becomes

5/20 = r⁴/r²

1/4 = r^(4 - 2)

(1/2)² = r²

r = 1/2
