The angles have equal measure because they are vertically opposite angles.
3x + 50 = 6x - 10
3x - 6x = -10 - 50
-3x = -60
x = 20
The answer is x=20.
Answer:
Step-by-step explanation:
To find the 41st term to 47th term, we must find the equation of how to get those terms.
The equation for arithmetic terms is , where d is the difference between two side-by-side terms.
By using this equation format, we get the equation
That means the terms are
Now to find the sum, we just add all the terms up simply
Sum = 82 + 84 +86 + 88 + 90 + 92 +94 = 616
Hope that helps!
Answer:
y=8
Step-by-step explanation:
the sum of the three angles is 180
