8.49 x 10^-7 = 0.000000849
answer
0.0000000849
Answer:
1 and four
Step-by-step explanation:
elg=124°
eld=2x
elg+eld=180°=>eld=180°-124°=56°/eld=2x=56°=>x=56°/2=28°
eld+dlh=180°=>dlh=180°-56°=124°
hlg+dlh=180°=>hlg=180°-124°=56°
B. the function of the graph approaches positive and negative infinity at x = -1
