The corresponding perimeter of the first triangle is 20 cm
<h3>Further explanation</h3>
Firstly , let us learn about trigonometry in mathematics.
Suppose the ΔABC is a right triangle and ∠A is 90°.
<h3>sin ∠A = opposite / hypotenuse</h3><h3>cos ∠A = adjacent / hypotenuse</h3><h3>tan ∠A = opposite / adjacent </h3>
Let us now tackle the problem!
<em>A similar triangle has the same angle, in other words the triangle has the same shape but different sizes.</em>
<em>We could calculate the perimeter of the first triangle by following formula:</em>
<h2>Conclusion:</h2>
The corresponding perimeter of the first triangle is 20 cm
