Find n 5|6n+15|+2=-43

Ivenika [448]

Answer:

<h2>No solution</h2>

Step-by-step explanation:

$5|6n+15|+2=-43\qquad\text{subtract 2 from both sides}\\\\5|6n+15|+2-2=-43-2\\\\5|6n+15|=-45\qquad\text{divide both sides by 5}\\\\\dfrac{5\!\!\!\!\diagup^1|6n+15|}{5\!\!\!\!\diagup_1}=\dfrac{-45\!\!\!\!\!\diagup^9}{5\!\!\!\!\diagup_1}\\\\|6n+15|=-9\qquad\bold{FALSE}\to\text{no solution}\\\\\text{because}\ |a|\geq0\ \text{for any real value of}\ a.$

How to find y in angle sum theorem

Svetach [21]

Answer:

y = 90°

Step-by-step explanation:

110° is the measure of exterior angle of bigger triangle.

-> (x + x) + 70° = 110° (By exterior angle theorem)

-> 2x = 110° - 70°

-> 2x = 40°

-> x = 40°/2

-> x = 20°

y is the measure of exterior angle of smaller triangle.

-> y = x + 70° (By exterior angle theorem)

-> y = 20° + 70°

-> y = 90°
