X=4
26x - 4 = 100
+4 +4
26x = 104
x = 104/26
x=4
We can use the cosine rule to find the third side:
c² = a² + b² -2abcos(C)
c = √(42² + 35² - 2(42)(35)cos(120)
c = 66.78
The answer is D.
Answer:
x = -26.67 (this is rounded the real answer is 26.6666...)
Step-by-step explanation:
180 - (46 + 36) = 82 (the measure of the last angle)
82 = (2 - 3x)
(subtract two from both sides)
80 = (-3x)
(divide both sides by -3)
-26.67=x
subtract 3 from both sides:

Multiply both sides by 2:

Subtract 3 from both sides:

Change sign to both sides (this implies that you should also change the inequality sign):

7/9. Solution: Graph it. It crosses the axis at y=-7 and x=9. Its rise is 7 and run 9.
