It would be 50
130+180= 310
360-310= 50
You get 180 from the missing side by 70 that becomes 180.
Answer:
Two Angles are Complementary when they add up to 90 degrees (a Right Angle)
Step-by-step explanation:

5 seconds
because that is the positive zero of that equation
First you need to get all variables on one side. You do that by multiplying the reciprocal of the fraction to everything.
N(5/1) x 1/5(5/1)=2/15(5/1)
5n=2/15 x 5/1
Then solve the multiplication problem
5n= 10/15
Then you should reduce the fraction
5n=2/3
Then divide both sides by 5
5n/5=N
2/3 divided by 5 =2/15
N=2/15
To form a linear pair means that when added, they equal 180 degrees.
but if they have equal measures....180/2 = 90...then they would both equal 90 degrees.....and 90 degrees is a right angle.
So ABC and CBD are both right angles
