Answer:
The third angle of the triangle is 90º
Step-by-step explanation:
A triangle has three interior angles.
The sum of the three interior angles of a triangle is 180º.
In this problem, we have that:
2 angles of 45º
A third angle x
The sum of these angles is 180. So
2*45 + x = 180
90 + x = 180
x = 90º
So
The third angle of the triangle is 90º

A polynomial is an expression that consists of variables (or indeterminate), terms, exponents and constants. For example, 3x2 -2x-10 is a polynomial.
Step-by-step explanation:
<u>In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. An example of a polynomial of a single indeterminate x is x² − 4x + 7</u><u>.</u>
