Answer:
Choice B
Step-by-step explanation:
If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent
-->
L is congruent to F; K is congruent to E; LK is congruent to FE
Which is ASA congruency
7x and x+20 lie on the straight line so they will equal to 180. So now we can add them and set them equal to 180 so we can solve for x.
7x + x + 20 = 180
8x + 20 = 180
8x = 160
x = 20.
So the value of x is 20

Answer: 50 holes
Step-by-step explanation: I find an easy way to answer questions like this is by 'dimensional analysis'....
Dimensions mins/holes and mins
mins / (mins/holes) = holes (because 'mins' cancel out)
25 mins / (6 mins/12 holes) = 300/6 holes = 50 holes
