23= 20
Add up the angles you know and subtract/add to figure out what value is missing to make it 180
Answer:
5
Step-by-step explanation:
The 32 that have blue and green ribbons include the 16 that have all three, so there are only 32 -16 = 16 that have only blue and green ribbons.
The 31 that have green and white ribbons likewise include the 16 with all three, so there are only 31 -16 = 15 that have only green and white ribbons.
The 38 that have blue and white ribbons include the 16 with all three, so there are only 38 -16 = 22 that have only green and white ribbons.

If we add the numbers of blue, green, and white ribbons, we are counting twice the numbers that have 2 ribbons, and 3 times the numbers that have 3 ribbons. We want to count each kind of ribbon-holder only once. Hence the number of individual dogs with any number of ribbons is only ...
62 +55 +63 -(16 +15 +22) -2(16) = 95
Of the 100 dogs, 95 have ribbons, so 5 dogs have not learned any tricks.
First find how they got 10 inches out of 25 centimeters.
25/10 = 2.5
This means that they divided 25 by 2.5 to get 10, and this pattern will continue throughout the whole table.
105 × 2.5 = 42
There are about 42 inches in 105 centimeters.
Another way to do this is there are 0.39 inches in 1 centimeter.
105 × 0.39 = 40.95
This rounds to 41.
This answer is probably better.
