Answer:

1. x=20 ; the angles are 90 degrees31 degrees 59 degrees

2. x=16; the angles are 16 degrees 92 degrees 72 degrees

Step-by-step explanation:

1. 180=90+31+(3x-1)

180-90-31=3x-1

59=3x-1

60=3x

x=20

plug in x for the third angle

2. 180= x+5x-8+3x+44

180=9x+36

180-36=9x

144=9x

x=16

plug in x to all the angles to find the real value

Which one of the following is not closed under the operation being performed

Sergeu [11.5K]

Remember that polynomials are closed under addition, subtraction, and multiplication, but they are not closed under division. The only division you have there is B; therefore the correct answer is B.

A. $(14x-2)3(x-2)=14 x^{2} -90x+10$ . The result is still a polynomial; therefore, answer A is incorrect.

B. $\frac{(14x-2)}{3(x-2)} = \frac{14}{3}$ with a remainder of 26. The result is not a polynomial anymore; therefore, B is the correct answer.

C. $(14x-2)+3(x+2)=17x+4$ . The result is still a polynomial; therefore, answer C is incorrect.

D. $(14x-2)+3(x+2)=17x+4$ . The result is still a polynomial; therefore, answer D is incorrect.
