Answer:
5
8
20
Step-by-step explanation:
Is the 12 and 7 together or.....
C.6 i think, sorry if it’s wrong but my reasoning was that 50 + 58 = 108 and the interior of a triangle is 180 degrees so then you would subtract 180 - 108 = 72, then i did some guess work plugging in the different answers into the equation and 11 x 6 + 6 = 72 which was the missing angle from before
Actually Welcome to the Concept of the parallel,lines
Since both the angles are corresponding angles, hence they are equal,so we get as,
7x+40 = 3x+112
===> 7x - 3x = 112-40
===> 4x = 72
===> x = 72/4 => 18
hence x = 18°
now angle A = 7(18)+40
A = 166°
hence, A = 166°
