Two rigid transformations are used to map jkl to mnq-the first is a translation of vertex l to vertex q. what is thesecond transformation? a. a reflection across the line containing lk. b.a reflection across the line containing jk. c.a rotation about point l. d.a rotation about point k.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
