1. it is right-angled triangle because it has a 90 degree angle.
Then put in some butter that will get you out
Use trigonometry to find L.
Tangent = opposite over adjacent on any right triangle.
tan(L) = 18/23
Take the inverse on both sides.
arctan(tan(L)) = arctan(18/23)
L = 38.0470425318
L = 38.05°
Done.
Answer:
$88
Step-by-step explanation:
-38+126=$88
65/100 or 13/20
Both work, it's just that 13/20 is simplified
