What is 8  23/100 as a decimal 

So since there is a mixed number, 8 means there are 8 one-hundreds and 23 remaining ones. So, 800+23=823 ones. 823/100 as an improper fraction. since it is already out of 100, your job is easy. you now divide 823 by 100 (move the decimal over to the left 2 places) and you get 8.23 as a decimal. Hope i helped!!

8 23/100

the ratio is 23/100 = (move the decimal of 23.0000 . . .  over the left two places since dividing by 100 = 10^-2)

23/100 = 0.23

8 + 0.23 = 8.23

answer is 8.23

All angles in triangle inside add up to 180
so

the angles are y, 79,37
therefor
y+79+37=180
solvde for y
y+79+37=180
add
y+116=180
subtract 116 from ot hsides
y=64

angle y=64 degrees
