MZJ and m M are base angles of isosceles trapezoid JKLM. If mZJ = 18x + 8 and m_M=11x + 15 find m2K.
maxonik [38]

The question is incomplete. Here is the complete question.

m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.

If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.

A. 1

B. 154

C. 77

D. 26

Answer: B. m∠K = 154

Step-by-step explanation: <u>Isosceles</u> <u>trapezoid</u> is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.

Related to internal angles, angles of the base are equal and opposite angles are supplementary.

In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:

18x + 8 = 11x + 15

7x = 7

x = 1

Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:

m∠J = 18(1) + 8

m∠J = 26

m∠K + m∠J = 180

m∠K + 26 = 180

m∠K = 154

The angle m∠K is 154°

<em>Answer:</em>

<em>D)</em>

<em>Step-by-step explanation:</em>

<em>We know that it cannot be C since z is not involved in this problem.</em>

<em>a) 3/20x</em>

<em>Try with 20 = x</em>

<em>3/440 ≠ 3</em>

<em>A is not the answer.</em>

<em>b) 60x</em>

<em>Try with 20 = x</em>

<em>1800 ≠ 3</em>

<em>B is not the answer.</em>

<em>c) 60/x</em>

<em>Try with 20 = x</em>

<em>3 = 3</em>

<em>Try with 15 = x</em>

<em>4 = 4</em>

<em>D is your answer.</em>

<em>Hope this helps. Have a nice day. Oh, and one more thing. Surprised to see I'm not stealing points?</em>
