Question

Given that the measure of ∠x is 20°, and the measure of ∠y is 30°, find the measure of ∠z.

Answer 1

Answer:

40°

Step-by-step explanation:

z+90+y+x=180°

z+90+30+40=180°

z=40°

Answer 2

Angle Z would be 40°

The top half of the image is 180° In total and the red square represents 90°,

And since angle X is 20° and angle Y is 30° thats 50° total leaving a total of 40° unknown for the top half making that 40°

Answer: Z=40°
