Wish I could help on so sorry
The complete question in the attached figure
we know that
sin40° = opposite side / hypotenuse
opposite side =AC
hypotenuse = AB-------> 10 in
so
sin 40=AC/AB---------> AC=AB*sin 40-------> AC=10*sin 40
the answer is
AC=10*sin 40
Answer:
90+15x=225
Step-by-step explanation:
90 already saved plus 15 an hour equals 225
The function is B, you can tell using the vertical line test through each point
