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>
Mr Welch bought 8 yard of fencing
Step-by-step explanation:
Mr Welch bought 24 ft of fencing
We need to find how many yards of fencing did he buy
We need to convert 24ft into yards
We are given 1 yd = 3ft
We can write
3 ft = 1 yd
then 1 ft will be:
1 ft = 1/3 yd
Now, 24 ft will be:
24 ft = 1/3*24
24 ft = 8 yard
So, Mr Welch bought 8 yard of fencing

11 would be the answer!
Step-by-step explanation:
Evaluate the power
Calculate the sum
Hope this helps! :)
1/2 Square equals to 1/4 equals to x over 5 2 Square
therefore 1/4 equals to x over 5 2 square
Equals to 1/4 equals to x over 5 * 4 you know that 2 square equals to 4
So now I'm going to solve for 1/4 equals to x of over 5 * 4 equals to 20
1/4 equals to x over 20
1/4 equals to 20 cross multiply
= 1\4 = x/20
= 4 * x = 20*1
4x = 20
divide both side by the coefficient of x
4x/4 = 20/4
x =5
