71 and the blank angle are a linear pair/supplementary angles, meaning that their sum is 180 degrees.

71 + y = 180

y = 109

The sum of the interior angles of a triangle is 180 degrees. Therefore, all of the angles inside of the triangle will add up to 180.

109 + 46 + x = 180

x = 25

Answer: x = 25 degrees

Hope this helps!

Answer:

A. x < 6 and x > - 28

Step-by-step explanation:

We have been given the following inequality;

| x+11 | < 17

We can replace the absolute value function by re-writing the inequality as;

-17< x+11<17

subtract 11 from both sides;

-17-11<x+11-11<17-11

-28<x<6

splitting this we have;

x<6

x>-28

<h3>Solution:</h3>

Given, side (a) = x+3
We know, surface area of a cube = 6a^2
Therefore, the surface area of the cube

<h3> </h3><h3> $6(x + 3) ^{2} \\ = 6( {x}^{2} + 6x + 9) \\ = 6 {x}^{2} + 36x + 54$ </h3><h3>Answer:</h3>

The answer is

${6x}^{2} + 36x + 54$
