Two angles of a triangle are 55 and 55 it has two sides of equal length which could it be?

a: acute isosceles

b: right scalene

c: acute scalene

d: obtuse isosceles

A.

Step-by-step explanation:

The third angle is  180 - 2*55 = 70 degrees.

So with 2 sides and 2 angles equal it is an acute isosceles triangle.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
