Answer:
21.98
Step-by-step explanation:
C=2πr C=2d are the formulas of circumference so that would mean the diameter of the circle is 7 since 2 times the radius is the diameter. We then multiply the diameter 7 by PI to get 21.98
Answer:
Step-by-step explanation:
180-143=37
NPI=180-37
NPI=143°
No because you would not be able to divide them by a number and get the same answer so no they are not proportional
Answer:
z = 23 degrees
Step-by-step explanation:
Total degree inside a triangle = 180
We can add up the 2 angles we got.
62 + 95 = 157
Subtract 157 from 180.
180 - 157 = 23
Check = the angle missing is an acute angle (less than 90 degrees) and 23 is less than 90 degrees so it is possible.
