Umm... not sure what her mistake is, but it should be 5.49+1.11=6.6
Answer: 118750000
Step-by-step explanation:
Population Then: 9.7 × 10^7 = 97000000
Each Year: 8.7 × 10^5 = 870000
After 25 Years People Added: 8.7 × 10^5 × 25 = 21750000
Population Now: 97000000 + 21750000 = 118750000
B since 11+11=22 and 3/7+4/7=1, 22+1=23
Answer:
x + 20° = 35.56°
3x + 10° = 56.68°
5x + 10° = 87.8°
Step-by-step explanation:
Assume;
Given measures are angle of a triangle
x + 20°
3x + 10°
5x + 10°
Find:
Value of each angle
Computation:
We know that, sum of all interior angle in a triangle is 180°
So,
We say that
x + 20° + 3x + 10° + 5x + 10° = 180°
9x + 40° = 180°
9x = 140°
x = 15.56°
So,
x + 20° = 15.56 + 20 = 35.56°
3x + 10° = 3(15.56) + 10 = 56.68°
5x + 10° = 5(15.56) + 10 = 87.8°
