<span>After you solve a system of linear equations, you will get an ordered pair (x,y). Replace x with whatever number you obtained for x, and replace y with whatever number you obtained for y. If both your equations are true upon simplifying, you know it is correct.</span>
30 = arc BC / 2
arc BC = 2(30)
arc BC = 60
answer
D. 60
Answer:
x=16º
Step-by-step explanation:
The sum of angles in a triangle is 180º.
So,
39 + 125 + x = 180
Solve for x.
164 + x = 180
x = 180-164
x= 16
