Answer:
it is possible to draw a triangle with angles 90 degree, 60degree and again 60 degree

so. hmm which is it? the +/- ? well, neverminding for a second, the value of tangent, just looking at the sign, the tangent is positive,
tangent = opposite/adjacent.... so that only happens, when both are the same sign, + or - both
now, we know the sine is -1/5.. if the sine is negative, the cosine also has t to be negative, so we'd use the -2√(6) = a
thus
A. 29
b. 36
c. 49
d. 61
...
the answer's a. 29.
Answer:
The area of the yard is;
5x^4 -2x^3+9x^2+50
Step-by-step explanation:
Here, we want to calculate the area of the yard
Mathematically, this can be calculated as the difference between the area of the plot and the base area of the house
So, we simply proceed to calculate a subtraction here;
Thus, we have this as;
5x^4 + 9x^2-4x -(2x^3-4x-50)
= 5x^4 + 9x^2-2x^3+ 50
Rearranging this, we have;
5x^4 -2x^3+9x^2+50
