If 2 angles are formed on a line, then they make a supplementary / linear pair of angles, i.e, both the angles form 180°.
Here,
Angle A = 80°
Angle B = x°
So,
Angle A + Angle B = 180°
80° + x° = 180°
x° = 180° - 80°
x° = 100°
=》 Angle B = 100°

Answer:
The probability that the next color will be red is: 
Step-by-step explanation:
The probability of an event is defined as:
Probability=(Total number of favourable outcomes)/(Total number of outcomes )
Here we have to find the probability that the next colour is red is given by:
<em>The recordings are given as:</em>
B R Y R R R R Y R B R R
Number of outcomes that red will come up=8
Total number of outcomes=12
Hence the probability is given by:

Answer:
a+b
a=8
b=19
8+19= 27
