Answer:
C D
Step-by-step explanation:
Answer:
x =21
Step-by-step explanation:
So we know that:
And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:
Now, solve for x. Add 30 to both sides. The left side cancels:
Now, subtract 2x from both sides. The right cancels:
Thus, the value of x is 21.
Answer:
60$ will be left
Step-by-step explanation: 30x8 = 240. subtract 300-240 and you get 60
Angle a and b are C) supplementary angles
