I do not understand :(

G'(-3, -2), E'(1, 1), W'(-3, 0)

Step-by-step explanation:

A point has coordinates (x, y).

A translation of h units to the right means add h to x.

A translation of h units to the left means subtract h from x.

A translation of k units up means add k to y.

A translation of k units down means subtract k from y.

The translation you need to do is 1 unit right and 2 units down.

That means add add 1 to x of each point. Subtract 2 from y of each point.

G(-4, 0) > G'(-4 + 1, 0 - 2) = G'(-3, -2)

E(0, 3) > E'(0 + 1, 3 - 2) = E'(1, 1)

W(-4, 2) > W'(-4 + 1, 2 - 2) = W'(-3, 0)

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
