x = 4
A line with an undefined slope is a vertical line parallel to the y-axis and passing through all points with the same x-coordinate. For this reason it's equation is x = c where c is the value of the x-coordinate it passes through.
line passes through (4, 3 )
Hence equation is x = 4
139 = x + (2x + 10)
139 = 3x + 10
129 = 3x
/3 /3
43 = x
Therefore
In geometry, the length of JK in terms of a, b, and x will be D. abx
<h3>How to illustrate the information?</h3>
It should be noted that from the information given, it was stated that in circle M, EMF measures the radians allocated, the length of radius FM is and the length of EF is x.
In the other circle, JNK also measures the radians allocated and the length of radius KN is b.
Therefore, the length of JK in terms of a, b, and x will be:
= a × b × x
= abx
