Answer:
square both sides
I.e,tan²0=3
from,tan²0 +sec²0 = 1
so,tan²0=1-sec²0
1 - sec²0=3
sec²0 = 1 - 3
sec²0=-2
square root both sides
sec0 =√-2
0.104
Step-by-step explanation:
10.40 · 0.01 = 0.104
320
25 + 15 = 40 toys each
Toy makers x number of toys each = total toys carved
8 x 40 = 320 totals carved in all
