Step-by-step explanation:
4-17x^2+16=0 s
Calculate multiply
20-17x^2=0
Reoder the term
-17x^2+20=0
Calculate the discriminat
D=0^2-4x(-17)x20
Simplify
D=1360
The quadric equation has 2 real solutions
So your Solution is :
2 real solutions
Answer:
38°
Step-by-step explanation:
∠4=∠2
∠2=∠6
∠6=38°
So ∠4=38°
1.168 rounded off to nearest thousands = 1168
Answer (prediction, first edit):
