Question

find the degree measure of the angles
In the given figure. z+20 z+40 z+30​

Answer 1

Answer:

so we know the sum of angles of a triangle is 180

z+20+z+40+z+30 = 180

3z + 90 = 180

3z = 90

z = 30

the angles are:

50

70

60

Answer 2

Answer:

z+40+z+30+z+20=180°

3z+90=180°

3z=180-90

z=90÷3=30

z+40=40+30=70

z+30=30+30=60

z+20=20+30=50
