8x + By + 92 = 0

(-4; 12) ⇒ x = -4; y = 12

subtitute

8 · (-4) + 12B + 92 = 0
-32 + 12B + 92 = 0
12B + 60 = 0 |subtract 60 from both sides
12B = -60 |divide both sides by 12

B = -5

What is the value of x

pochemuha

This is the isosceles triangle. Therefore, the angles at the base are congruent.

We know that the sum of the measures of the angles in a triangle is 180°.

Therefore we have the equation:

$38^o+x^o+x^o=180^o$

$38^o+2x^o=180^o$ <em>subtract 38 from both sides</em>

$2x^o=142^o$ <em>divide both sides by 2</em>

$x^2=71^o$

<h3>Answer: x = 71.</h3>
