there are 10 pairs of numbers
they add to 21
10 times 21=210
the sum is 210
Answer:
17.1972degrees
Step-by-step explanation:
length of an arc = theta/360 * 2πr
Substitute the given angle;
1.2 = theta/360 * 2(3.14)(4)
1.2 = theta/360 * 25.12
1.2/25.12 = theta/360
0.04777 = theta/360
theta = 360 * .04777
theta = 17.1972
Hence the required angle is 17.1972degrees

Since your question doesn’t include the options:
I could help you determine which one in your given choices is parallel to y = 2/7x - 5.
Parallel lines have the same slope. Given that the slope y = 2/7x - 5 is 2/7, then the slope of the other line must also be 2/7.
