Answer:

total profit gained = 20%

Step-by-step explanation:

profit = SP - CP = 18 - 15 = 3 naira

total profit percentage =

  • ( profit / CP ) × 100
  • 3 / 15 × 100
  • 20%

Need help with trigonometry
vovangra [49]

Answer:

\sf \tan(A) & =\dfrac{9\sqrt{22}}{44}

Step-by-step explanation:

If angle C is the right angle, then side c is the hypotenuse.

Use Pythagoras' Theorem a^2+b^2=c^2 to find the length of side a:

Given:

  • b = 2√22
  • c = 13

\implies a^2+(2 \sqrt{22})^2=13^2

\implies a^2+88=169

\implies a^2=81

\implies a=\sqrt{81}

\implies a=9

<u>Tan Trig Ratio</u>

\sf \tan(\theta)=\dfrac{O}{A}

where:

  • \theta is the angle
  • O is the side opposite the angle
  • A is the side adjacent the angle

Given:

  • \theta = A
  • O = side opposite angle A = a = 9
  • A = side adjacent angle A = b = 2√22

\begin{aligned}\implies \sf \tan(A) & =\dfrac{9}{2\sqrt{22}}\\\\ & =\dfrac{9}{2\sqrt{22}} \times \dfrac{\sqrt{22}}{\sqrt{22}}\\\\ & = \dfrac{9\sqrt{22}}{44} \end{aligned}
