Answer:
x = 9
Step-by-step explanation:
You can solve this problem by isolating the variable.
3-√x = 0
√x = 3 (add √x to both sides of the equation)
x = 9 (square both sides of the equation)
Answer:
B
Step-by-step explanation:
Answer:
84°
Step-by-step explanation:
smallest angle=x
3x=2nd angle
x+40=3rd angle
angles in a triangle add up to 180 degrees so
5x+40=180
5x=140
x=28
largest angle = 3x
so 3 x 28 = 84 degrees
The largest angle is 84 degrees
