Answer:

x = 18°

$\angle A = 73°$

Step-by-step explanation:

By interior angle property on the same side of transversal.

$\angle A + \angle B= 180°\\(6x-35°) + (3x+53°)=180°\\9x + 18° = 180°\\9x = 180° - 18°\\9x = 162°\\x = \frac{162°}{9}\\\huge \purple {\boxed {x = 18°}} \\\angle A = 6x - 35°\\\angle A = 6\times 18°- 35°\\\angle A = 108°- 35°\\\huge \red {\boxed {\angle A = 73°}} \\$

Answer:

$smaller \: x = \boxed { - 5} \\ larger \: x = \boxed 2$

Step-by-step explanation:

$5 {x}^{2} + 15x - 50 = 0 \\ 5( {x}^{2} + 3x - 10) = 0 \\ {x}^{2} + 3x - 10 = 0 \\ {x}^{2} + 5x - 2x - 10 = 0 \\ x(x + 5) - 2(x + 5) = 0 \\ (x + 5)(x - 2) = 0 \\ x + 5 = 0 \: or \: x - 2 = 0 \\ x = - 5 \:or \: x = 2 \\ smaller \: x = \boxed { - 5} \\ larger \: x = \boxed 2$
