The angles add up to 180°.

The triangle is obtuse.

It is an isosceles triangle.

The angles add up to 180°.

Step-by-step explanation:

Obtuse triangles are defined as triangles with one angle obtuse angle over 90°. This triangle has an angle of 100°, so it is an obtuse triangle!

Isosceles triangles have 2 equal sides. The two orange dashes on the left and right legs of the triangle tell us they are equivalent, so this is an isosceles triangle as well!

Finally, all triangles add up to 180°! We can prove this by adding the angles.

40° + 40° = 80°

100° + 80° = 180°

The triangle is obtuse.

It is an isosceles triangle.

The angles add up to 180°.

Step-by-step explanation:

Correct statements and reasons are in bold.

The triangle is acute. No, since one angle is obtuse.

The triangle is obtuse.  Yes, because it has an obtuse angle.

It is an isosceles triangle.  Yes, because 2 sides are congruent.

It is a scalene triangle.  No, since 2 sides are congruent.

It is an equilateral triangle.  No, since not all sides are congruent.

The angles add up to 180°. Yes because that is true for every triangle.

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
