Answer:
C. Cos(60°) = Sin(30°)
Step-by-step explanation:
Cos(60°) = 0.5
Sin(30°) = 0.5
(sinx + cosx)^2/((sinx)(cosx)) = 2 + (secx)(cscx)
<span>(sinx + cosx)^2/((sinx)(cosx)) = 2 + 1/(sinxcosx); subtract 1/sinxcosx both sides </span>
<span>(sinx + cosx)^2/((sinx)(cosx)) - 1/(sinxcosx)= 2; multiply through by sinxcosx </span>
<span>(sinx + cosx)^2 -1 = 2(sinxcosx) </span>
<span>sin^2 + 2sinxcosx + cos^2 - 1 = 2(sinxcosx); since sin^x + cos^2x = 1 </span>
<span>1 + 2sinxcosx -1 = 2sinxcosx </span>
<span>2sinxcosx = 2sinxcosx</span>

No, it’s not a linear equation.
Answer:
Area of shaded region = 119.44 cm²
Step-by-step explanation:
Area of circle = πr²
= 3.14 × 2²
= 3.14 × 2 ×2
= 12.56 cm²
Area of rectangle = length × breadth
= 11cm × 12cm
= 132 cm²
Area of shaded region = Area of rectangle - Area of circle
= (132 - 12.56) cm²
= 119.44 cm²
