Answer:
x=-8
Step-by-step explanation:
the equation is in standard form of y=ax^2+bx+c
so, to find the vertex, or axis of symmetry do -b/2a.
-16/2(1)=
-8
8 inches is the answer first you divide 23 by 2 which gives you 11.5 then 92÷11.5=8 you do it this way because of the formula you use for area with a triangle 1/2 base times height
If you want the common denominator, then 1/2 is 4/8. I hope that answers your question :)

Answer:
Step-by-step explanation:
<u>Use cosine:</u>
- cos = adjacent / hypotenuse
- cos ∠L = KL/JL
- cos 21° = 4/x
- x = 4 / cos 21°
- x = 4.3 (rounded)
