Answer:
The missing angles measure is 70 degrees
Step-by-step explanation:
First we must complete the left triangles last measure:
60+65+x=180
x=55
Then we have to make all of those three middle angles equal 180:
55+50+y=180
105+y=180
y=75
Now we add 75 to 35 to the missing angle to get 180:
75+35+z=180
110+z=180
z=70
The missing angles measure is 70 degrees
2r + 2r + 5 + r + 4r - 3 = 38
9r + 5 - 3 = 38
9r + 2 = 38
9r = 38 - 2
9r = 36
9r/9 = 36/9
r = 4cm
Done!
