Since the 100 degree angle is the same as the m + 20 degree angle, you only have to do: 100-20=80
So the answer is 80

Answer:
The selling price is $28.75b.
Step-by-step explanation:
There are no options given but I will represent the word problem mathematically.
Let b stand for all the birdbath. If the owner pays $25 for each, then he pays $25b.
Selling them for 15% more means, 15% of the cost price was added to the original price. Finding 15% of cost price we have:
15% x $25b = 0.15 x $25b = $3.75b.
Therefore, the selling price is given as
$25b + $3.75b = $28.75b.
<span> | 3 - 6x | = 15
3-6x = 15
-6x = 15 -3
-6x = 12
x = -2
</span>-(3-6x) = 15
-3+6x = 15
6x = 15 +3
6x = 18
x =3
solutions x = -2 and x = 3
