Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
we have that
The cosine of angle theta is negative and the tangent of angle theta is positive
That means that the sine of angle theta is negative
step 1
Find 
we know that
we have
substitute
square root both sides
Remember that
In this problem the sine of angle theta is negative
so
step 2
Find 
we know that
we have
substitute the given values
The rate in m³/m² is 40m³/m².
1 m³ is literally a cube with sides that are 1 m in length. 1 m = 100 cm, so each side of this cube is 100cm in length. Finding the volume means multiplying length by width by height:
100(100)(100)=1,000,000 cm³ in 1m³.
We know that we have 25,000cm³ of mulch; we divide to find how many cubic meters this is:
1,000,000/25,000 = 40 m³.
This makes the rate 40m³/m².

So u will do 88+84=172+88=260+91=351 and that is all four tests added up now u have to divide the answer by 4 because it was four tests averages
351/4=87.75 wich is aproxamately 88
so with all four of them added wich is 351 u will add the answer choices so 351+96=447/5=89.4 wich is aproxamately 89
351+97=448/5=89.6 wich is aproxamately 90
351+98=449/5=89.8 wich is aproxamately 90
351+99=450/5=90
so i would say that 99 points is the one she needs to score because it isnt asking for aproxamately
so it is 99 points

Answer: She messed up in Step 1
She first should of tried to factor it first. There she can see that 3 and -11 work together in order to get (x+3)(x-11)
x= -3 and x=11
