Answer:
There are 29 triangles when you count them all including non obvious ones.
<span>probability of getting 4 or 6 is 1/6 + 1/6 = 2/6 = 1/3</span>
B= 20°
and c = 160°
b is equal to the given angle, b = 20°
c is 180 - 20 = 160°
The answer is a=7 because you have to do 7-6 which equals to 2 which a=7 is the right answer
8x+324 is the answer, all you have to do is multiple 6 times 54
