What additional information is needed to prove the triangles are congruent by the hl theorem?
explain

Line KL is congruent to Line BC

Step-by-step explanation:

If we find this we can get the HL Postulate. There is a right angle, we have one side, all we need is one more side that is opposite of the right angle. KL and CB.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

b. x- 48 =120
