Answer:
x = 21
Step-by-step explanation:
Sum of interior angles in a triangle = 180
so
3x + x -4 + 100 = 180
4x + 96 = 180
4x = 84
x = 21
Answer:
x = 21
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
3x + 100 + x - 4 = 180 ← simplify the left side
4x + 96 = 180 ( subtract 96 from both sides )
4x = 84 ( divide both sides by 4 )
x = 21

51-38=8 and 44-38=8 are both equivalent
Answer:
9x is the answer
Step-by-step explanation:
-x-(-10x)
-x+10x
9x
I think it would be 8-3, not 7. 8x - 2x + 5x = (8-5)x + 5x
LCM of 12 and 17 = 204
Hope this helps!
