Answer:
A)
Step-by-step explanation:
in a 30-60-90 triangle the sides, respectively, are in the ratio of 1 : : 2
∠ KLM = 27°
∠ KLM + ∠ NLM = 90 , that is
3x + 7x = 90
10x = 90 ( divide both sides by 10 )
x = 9
Thus
∠ KLM = 3x = 3 × 9 = 27°
The slope is 1/6
C. y=2x+1
2×3=6
6+1=7
2×0=0
0+1=1
2×-1=-2
-2+1=-1
therefore answer=C
