36°.
Since all the angles in a triangle are equal to 180°, you can find x by doing 2x+2x+6x=180.
Combine like terms and you get 10x=180. Divide both sides by 10 and you get x=18.
Sub in 18 for x at angle C and you get 2(18), which equals 36°.
Hope this helps!
You can use properties to solve equations with variables on both side by simplifying get the variable on one side. solve using inverse operations then check to see if it fits in right .
Answer:
w = -20
Step-by-step explanation:
Solve for w:
4 - 2 (1 - w) = -38
Hint: | Distribute -2 over 1 - w.
-2 (1 - w) = 2 w - 2:
2 w - 2 + 4 = -38
Hint: | Group like terms in 2 w - 2 + 4.
Grouping like terms, 2 w - 2 + 4 = 2 w + (4 - 2):
2 w + (4 - 2) = -38
Hint: | Evaluate 4 - 2.
4 - 2 = 2:
2 w + 2 = -38
Hint: | Isolate terms with w to the left hand side.
Subtract 2 from both sides:
2 w + (2 - 2) = -2 - 38
Hint: | Look for the difference of two identical terms.
2 - 2 = 0:
2 w = -2 - 38
Hint: | Evaluate -2 - 38.
-2 - 38 = -40:
2 w = -40
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 2 w = -40 by 2:
(2 w)/2 = (-40)/2
Hint: | Any nonzero number divided by itself is one.
2/2 = 1:
w = (-40)/2
Hint: | Reduce (-40)/2 to lowest terms. Start by finding the GCD of -40 and 2.
The gcd of -40 and 2 is 2, so (-40)/2 = (2 (-20))/(2×1) = 2/2×-20 = -20:
