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 = 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)

Decide whether each number is written in standard notation or scientific notation.

VARVARA [1.3K]

The answers are as follows:

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7 - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation

Concept: Standard notation is a way of writing a number so it is easier to read. It is often used for very large or very small numbers.

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

In the given questions,

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7 - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation

What is an algebraic expression for the word phrase?<br> the difference of a number r and 3

Ostrovityanka [42]

Answer:

r - 3

Step-by-step explanation:

The word "difference" means that it's a subtraction problem

so the difference between r and 3 is r - 3
