This is the concept of polynomial equations. Suppose we are given the binomial equations;
(a+b)^2
=(a+b)(a+b)
=a^2+2ab+c^2
The above answer is a trinomial, from this we can deduce that the square of a binomial is always a trinomial
Answer:
60
Step-by-step explanation:
The sum of the angles of a triangle is 180
x+x+x = 180
3x= 180
Divide by 3
3x/3=180/3
x = 60
