Given oblique △abc

use the properties of right triangles and △abc to prove the law of sines.
find the length of bc, rounded to the nearest tenth of a unit.
in your final answer for parts a and b, include all of the necessary steps and calculations.

Step-by-step explanation:

Law of sines states that a/SinA = b/SinB = c/SinC

Substitute

a/Sin46  = 17/Sin31

a/0.71933980 = 17/0.51503807

a/0.71933980 = 17/0.51503807

a/0.71933980  = 17/0.51503807

a/0.71933980  = 33.00726876

Multiply by 0.71933980

a = 23.7434421

Since BC = a, BC = about 23.7 units

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
