Answer:
Polynomials in one variable are algebric rcpressions that consist of terms in the form axn a x n where n id a non-negayive(i.e positive or zero)integer and a is a real number and is called the coefgicient of the term.The degree of polynomial in ine variable is the largest exponent in the polynomial.
Answer:
The height of the flagpole is 7.5 m
Step-by-step explanation:
In this problem
we know that
Triangles SPN and SFG are similar by AA Similarity Theorem
see the attached figure to better understand the problem
Remember that
If two figures are similar then the ratio of its corresponding sides is proportional
so
SN/SG=PN/FG
we have
SN=8 m
SG=SN+NG=8+32=40 m
PN=1.5 m
FG ----> the height of the flagpole
substitute the values and solve for FG
8/40=1.5/FG
Multiply in cross
FG(8)=40(1.5)
FG=40(1.5)/8
FG=7.5 m
Value of cos(x+π) =
Given cosine of x =
i.e., cos(x) =
Also cos() = . So x = .
We need to find cos(x+π) = cos().
But its value is not easy to find. So we use trigonometric formulas.
We have the trigonometric formula, cos (x+π) = - cos(x) = - =
Cos(x+π) lies in the 3rd quadrant. So there cosine has negative values. That is why, cos (x+π) = - cos(x).

The sum of the angles in a triangle is 180°, so the angles do form a triangle. Since two of the three angles are congruent, the triangle is an isosceles triangle. An infinite number of isosceles triangles exist with different side lengths. Therefore, more than one triangle<span> exists with the given angle measures.</span>
