TIP:
74.90*.2=14.98
74.90+14.98=89.88
TOTAL:
89.88/5=17.98

Answer:
x = √2/2
Step-by-step explanation:
Use the identity:
arcsin x + arccos x = π/2
Therefore, we can rewrite this as:
arcsin x (π/2 − arcsin x) = π²/16
If we substitute y = arcsin x:
y (π/2 − y) = π²/16
π/2 y − y² = π²/16
0 = y² − π/2 y + π²/16
0 = 16y² − 8π y + π²
0 = (4y − π)²
y = π/4
Substituting back:
arcsin x = π/4
x = sin(π/4)
x = √2/2
Step-by-step explanation: Begin by studying the pattern.
Notice that if we divide the first term,
360, by 6, we get the second term, 60.
Similarly, if we divide the second term,
60, by 6, we get the third term, 10.
So each new term is equal to the previous term
divided by 2, so we use this idea to find any missing terms.
It’s figure B it’s the same as figure 1
