Likurg_2 [28]

Answer:

angle A=30°

Step-by-step explanation:

$9x + 6 + 4x + 6 + 90 = 180 \\ 13x + 102 = 180 \\ 13x = 180 - 102 \\ 13x = 78 \\ \frac{13x}{ 13} = \frac{ 78}{13} \\ x = 6 \\ 4x + 6 = a \\ 4(6) + 6 = a \\ 24 + 6 = a \\ 30 = a$

SOVA2 [1]

You would spend about 46.3 hours driving

Step-by-step explanation:

To drive from New York City, to Los Angeles,

You must drive about 2,779 miles
You drive 60 miles per hour

We need to find about how many hours you would spend driving

∵ The distance you must drive = 2,779 miles

∵ You drive 60 miles per hour

∵ Distance = speed × time

- Substitute the distance and speed in the rule above

∴ 2,779 = 60 × time

∴ 46.32 = time

∴ The time is about 46.3 hours

You would spend about 46.3 hours driving
