As you see this is a right angle, so the sum of the two angles = 90°
So,
(x + 42) + 3x = 90°
Remove the parentheses:
x + 42 + 3x = 90
Combine like terms:
4x + 42 = 90
Subtract 42 on both sides:
4x = 48
Divide 4 on both sides:
x = 12

Answer:
1) 2.71%
2) $38.32
Step-by-step explanation:
Opening balance = $1220
Balance after 10 days (after expense) = $1690
Balance after 10 days(after payment) = $1340
APR = 33%
1) Periodic interest rate = APR × 
= 33%× 30/365
= 2.71%
2) Interest charged for first 10 days = 
= $11.02
Interst charged for the next 10 days = 
= $15.2
Interest charged for the next 10 days = 
= $12.10
Total interest for 30 days = 11.02+15.2+12.10
= $38.32
Unsecured credit cards could possibly be the answer
Density = m/v
3.86kg=3860g
d= 3860/200
= 19.3g/cm^3
therefore it is gold.
