Can't seem to get this one, ? (20pt)

The answer to your question is:     (∞ , 3]

Step-by-step explanation:

Remember that to express an inequality, are used ( ) and [ ].

(  ) are used when the point is not consider in the interval.

[  ]  are used when the point is consider or is part of the interval.

Also, an empty point indicates that the number is not consider in the interval.

and, a filled point indicates that the number is consider in the interval.

For your question, the interval will be:

                               (∞ , 3]

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
