Find the measure of angle C of a triangle ABC, if: m∠A = ∝, m∠B = 2∝
Effectus [21]

Answer:

The measure of ∠ C is 180°-3∝

Step-by-step explanation:

We are given a ΔABC

∠A = ∝

∠B = 2∝

Angle sum property of triangle : The sum of all angles of triangle is 180° is called angle sum property of triangle

So, ∠A+∠B+∠C=180°

∝+2∝+∠C=180°

3∝+∠C=180°

∠C=180°-3∝

Hence the measure of ∠ C is 180°-3∝

7. Which property of polynomials says that the sum of two polynomials is also a polynomial?
vlabodo [156]

Answer:

Closure property

Step-by-step explanation:

The closure property of polynomials for addition says that, if we add any two polynomials , the result is also a polynomial.

For is

{x}^{2}  + 2

is a polynomial.

x - 2

is also a polynomial.

The sum of the two polynomials is

{x}^{2}  + 2  + x - 2 =  {x}^{2} + x

The result:

{x}^{2}  + x

is also a polynomial.
