Answer:
the angles s and r are supplementary so 180 - 40 = 140
Step-by-step explanation:
Answer:
In the given expression x:6 :: 3:9 , x = 2
Step-by-step explanation:
Here, the given expression is:
x:6 :: 3:9
or, x : 6 = 3 :9
So, by the RATIO OF PROPORTIONALITY:

or, x = 2
Hence, in the given expression x:6 :: 3:9 , x = 2
That the answer, I hope that will help you

So, you already know that angle CBD is 68 degrees, and the complementary angle to angle CBD is angle CBA. These angles together make 180 degrees because segment DBA is a straight line consisting of angles CBD and CBA. 180-68(the angle you already know) is 112 degrees for angle CBA. Then you repeat this process to find the other angles
