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:468 in2
Step-by-step explanation:
248 to 370 gems
set up two equations
132=(1/2)x+8 x=248
193=(1/2)x+8 x=370
