r<9
Step-by-step explanation:
r/3 + 5 < 8
Subtract 5 from each side
r/3 + 5-5 < 8-5
r/3 < 3
Multiply each side by 3
r/3 *3 <3*3
r<9
40 million foreign-born representing 13% of the population resided in the United States. The chart below shows the trends by decade, 1860-2010. It is adapted from the more detailed table that follows, which appears in Audrey Singer’s article,
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°
