Answer:
6.88
Step-by-step explanation:
Evaluating the tangent function for the two values we obtain the following:
tan 135=tan(135+180)=tan 315=-1
next:
tan -135=tan(180-135)=tan 45=1
thus comparing the two we see that tan 135 is negative while tan -135 is positive
Answer:
131
Step-by-step explanation:
(-48)+(-110)+27
Remember one of the most important math rules
- * - = +
-*+= -
+*+ =+
+*-=-
That been said
We can now perform the operation
-48-110+27= -131
