Hey there!
An obtuse angle is defined as an angle that is wider than 90° but less than 180°. For example, a 68° would not be considered obtuse, but a 107° would. As long as the degree is between 90 and 180, the angle is obtuse. Any other angle (either between 0 and 90 OR 180 and 360) is not obtuse.
You can use this information to answer the question based on the angles you have been given.
Hope this helped you out! :-)
Remember that X will always be one up or down depending on if there is a - or not (if it is just an x) and one over! Hope this helps

Answer:
c = 36.06
Step-by-step explanation:
a² + b² = c²
20² + 30² = c²
400 + 900 = c²
c² = 1300

c = 36.06
$36.8 because if you do 40 times .08 you get 3.2, after that you do 40-3.2 and you get 3.8. Hope this helps.
