<h3>given:</h3>

$2d^4-13d^2-45$

<h3>let's solve:</h3>

$2d^4-13d^2-45$

$2 {d}^{4} + 5 {d}^{2} - 18 {d}^{2} - 45 \\ {d}^{2} ( {2d}^{2} + 5) - 9( {2d}^{2} + 5) \\ ( {2d}^{2} + 5)( {d}^{2} - 9 )\\ ( {2d}^{2} + 5)(d + 3)(d - 3)$

Which BEST describes the construction of a triangle if given one side length of 10 cm and one right angle?

Colt1911 [192]

Statements that best describe the triangle are the following:
1. It is a right triangle, therefore one angle is equivalent to 90°.
2. We can solve for the measurement of the other leg using the Pythagorean theorem c²=a²+b².
3. We can use SOH CAH TOA theorem in solving the other unknowns.
