Answer:
C. Sometimes
Step-by-step explanation:
Placement of the c could indicate a rotated rectangle.
there are nine ducks and 3 swans
sqrt of 9 equals 3
3 + 9 = 12
Answer:
Step-by-step explanation:
∠UST=2 m∠2
10x+10=2(6x-1)
10x+10=12x-2
12x-10x=10+2
2x=12
x=6
m∠UST=10×6+10=70°
Answer:
Trinomial
Step-by-step explanation:
Hope it helps
First way
arcsin(1/4) means that 1/4 sin of the angle.
sin(α)=1/4
sin²α+cos²α=1
(1/4)²+cos²α=1
cos²α=1-1/16 =15/16
cosα=+/-(√15)/4
<span>Second way
</span>
sin(α)=1/4 =opposite leg/hipotenuse
cos(α)=adjacent leg/hypothenuse
adjacent leg =√(hypotenuse²- Opposite²)=√(16-1)=√15
cosα=+/-√15/4
For one value of sinα, possible 2 values of cosα.
