I believe you only need to know one angle.
For example, if you know angle 1, you can calculate angle 3. Angle 2 = angle 3 and angle 4 = angle 1.
Also, Angle 5= angle 1 and so on...
You can add the numbers together so:
12.6
3.1
<u>+ 5.4
</u> 21.1
<u>
</u>Since the sum of the numbers is 21.1, it is greater than 20<u>

Answer:
Step-by-step explanation:
14.)
lets first find x:
2x+x+90=189
3x=90
x=30
lets find y:
2y=x
2y=30
y=15
lets find z:
2y+z=180
30+z=180
z=150
