Initial investment = $775
Monthly investments = $C
Period of investment = 1 year = 12 months
Total monthly investments = Monthly amount*12 = C*12 = 12C
Total investment after 12 months = Initial investment + Total monthly investments = 775 + 12C
Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting :
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side
Answer:
∠ 1 = 20°, ∠ 2 = 160°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles and are supplementary, that is sum to 180°
x - 12 + 5x = 180 , that is
6x - 12 = 180 ( add 12 to both sides )
6x = 192 ( divide both sides by 6 )
x = 32
Thus
∠ 1 = x - 12 = 32 - 12 = 20°
∠ 2 = 5x = 5 × 32 = 160°
