Answer is they are parallel.
You know they are parallel because they both have a slope of 3.
Same slope= parallel

Parallel lines will go on forever, never crossing or intersecting. They stay side by side.

Solve the triangle. Round your answers to the nearest tenth.

Answer:

m∠A ≈ 43°

m∠B ≈ 55°

mBC ≈ 20

Step-by-step explanation:

Law of Sines: $\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Step 1: Find m∠B

$\frac{29}{sin82} =\frac{24}{sinB}$

Step 2: Solve for ∠B

29sinB = 24sin82°

sinB = 24sin82°/29

B = sin⁻¹(24sin82°/29)

B = 55.038°

Step 3: Find m∠A

180 - (55.038 + 82)

180 - 137.038

m∠A = 42.962°

Step 4: Find BC

$\frac{29}{sin82} =\frac{BC}{sin42.962}$

Step 5: Solve for BC

29sin42.962° = BCsin82°

BC = 29sin42.962°/sin82°

BC = 19.9581

A particular computer takes 12 minutes to download a 36 minute TV show. how long will it take the computer to download a 1.5 hr

Let x = movie download time
$\frac{12}{36} = \frac{x}{90}$
$36x = 1080$
$x = 30$
30 minutes
