Question

Plz help me! I don’t understand this :( 3 and 4 plz

Answer 1

Answer:

Explanation:

3. Find y:

Angle W + Angle I + Angle N = 180 degree (sums of Angle in a triangle)
(2y + 7) + (6y) + (8y + 13) = 180 degree
2y + 7 + 6y + 8y + 13 = 180
16y + 20 = 180
16y = 160
y = 160/16
y = 10

Thus, Y = 10
