2 and 3/4=2+3/4
1 and 1/3=1+1/3
2 and 3/4 minus (1 and 1/3)
2+3/4-(1+1/3)
2+3/4-1-1/3
2-1+3/4-1/3
1+3/4-1/3
make bottom number same
3/4-1/3
3/4 times 3/3=9/12
1/3 times 4/4=4/12
3/4-1/2=9/12-4/12=5/12
1+5/12
1 and 5/12
Answer:
50%
Step-by-step explanation:
We know that
if <span>90° < θ < 180°
</span>then
θ--------------> belong to the second quadrant
so
tan θ is negative
sin² θ + cos² θ=1----------> sin² θ=1-cos² θ----->sin² θ=1-(-2/9)²
sin² θ=1-(4/81)------> 77/81----------> sin θ=√(77/81)------> √77/9
sin θ=(√77)/9
tan θ=sin θ/cos θ------> [(√77)/9]/[-2/9]-------> -√77/2
the answer is the option
<span>A) -77sqroot/2</span>
