Enter your answer and show all the steps that you use to solve this problem in the space provided
serious [3.7K]

Since the two slant sides have equal length, the triangle is isosceles.

If a triangle is isosceles, the two angles at the base have equal measure.

So, the measures of the angles are 38, x and x. The sum of the angles is 180, so we have

38+x+x=180 \iff 2x=180-38 \iff x=\dfrac{180-38}{2}=71

The quotient of (x4 – 3x2 + 4x – 3) and a polynomial is (x2 + x – 3). What is the polynomial?
weeeeeb [17]
X/y=z
if we know x and z

solve for y
x/y=z
times both sides by y
x=zy
divide both sides by z
x/z=y

therefor
(x^4– 3x2 + 4x – 3)/?=(x^2+x-3)
so
\frac{x^4-3x2 + 4x-3}{x^2+x-3}=?
solve
first factor them
\frac{(x^2+x-3)(x^2-x+1)}{x^2+x-3}=?
x^2-x+1=?
the poly is x^2-x+1
