Short Answer

Expert verified

The solution for triangle ABC, is $a = 6, c = 8.5 and B = 45 °$ .

Step by step solution

Step 1. Write down the given parameters of triangle.

The given triangle ABC is shown below whose parameters are represented as $A = 45 {}^{\circ}, C = 90 {}^{\circ}{and} b = 6$ .

Step 2. Calculation.

In triangle ABC, $A = 45 {}^{\circ}, C = 90 {}^{\circ}{and} b = 6$ . Therefore, $B = 45 °$ by angle sum property.

Now $\begin{matrix} ∠ A = ∠ B gives, .... (45 ° each) \\ a = b \\ a = 6 \end{matrix}$

Now, in isosceles right triangle ABC,

$\begin{matrix} c = \sqrt{a^{2} + b^{2}} gives, \\ c = \sqrt{6^{2} + 6^{2}} \\ c = 6 \sqrt{2} \\ c = 8.5 \end{matrix}$

Step 3. Conclusion.

Thesolution for triangle ABC, is $a = 6, c = 8.5 and B = 45 °$ .
