Answer:
x ≤ 7/6
Step-by-step explanation:
12x - 5 ≤ 9 (add 5 to both sides)
12x ≤ 9 + 5
12x ≤ 14 (divide both sides by 12)
x ≤ 14/12
x ≤ 7/6
The second and third ones are the true ones
Answer:
34°
Step-by-step explanation:
If we assume that the acute angles in the triangle are 2x and (x+6), then we have ...
2x +(x +6) = 90
3x +6 = 90 . . . . . . simplify
x + 2 = 30 . . . . . . . divide by 3
x = 28 . . . . . . . . . . subtract 2
Then the angles are ...
2x = 2(28) = 56
x+6 = 28+6 = 34
The smallest angle is 34°.
