Answer:
a = 64°
b = 138.7°
Step-by-step explanation:
First, Let's find the measure a,
- 180° = 116° + a
- 180 - 116 = a
- a = 64°
______
Now,
- 90° + a + 82° + x + x + x = 360°
- 90+ 64 + 82 + 3x = 360°
- 236 + 3x = 360
- 3x = 124/ 3
- x = 41.3°
______
Now that we found out what x equals, let's find 'b'-
- b + x = 180°
- b + 41.3 = 180
- b = 180 - 41.3
- b = 138.7°

Answer:
.45 miles
Step-by-step explanation:
27 mph - How many miles per minute
We already know that there are 60 seconds in an hour. So the best thing to do in this situation is to divide the miles per minute.
27/60 = 0.45
.45 miles per minute
As a fraction, your answer would be 9/20
3 to the second power would be 9 .
3 to the fifth power would be 243 .
