Consider the two triangles shown. Which of the triangle congruence theorems could be used to prove the triangles congruent witho

Georgia [21]

Answer: AAS

Step-by-step explanation:

In the given triangles, there are two angles such as $84^{\circ}$ and $39^{\circ}$ and one non included side as 16 cm of both triangles are equal or congruent.

Thus, by AAS postulate of congruence both the triangles are congruent without establishing any additional information.

<em>The AAS postulate says that if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.</em>

Solve for x ! problems attached please help!!

vampirchik [111]

Answer:

7. $x\le 8$

8. $x\le 1.7$

9. $-0.2\le x\le 2$

10. $3< x\le 4$

Step-by-step explanation:

7. Solve for x:

$4x+7-x\le 31$

Separate variable and numbers into different sides of inequality:

$4x-x\le 31-7\\ \\3x\le 24$

Divide the inequality by 3:

$x\le 8$

8. Solve for x:

$2(x-3)+8x\le 11$

Eliminate the brackets:

$2x-6+8x\le 11$

Separate variable and numbers into different sides of inequality:

$2x+8x\le 11+6\\ \\10x\le 17$

Divide the inequality by 10:

$x\le 1.7$

9. Solve for x:

$-7x\le 3x+2\le 8$

Solve two inequalities $-7x\le 3x+2$ and $3x+2\le 8$ separately:

$-7x\le 3x+2\\ \\3x+2\ge -7x\\ \\3x+7x\ge -2\\ \\10x\ge -2\\ \\x\ge -0.2$

and

$3x+2\le 8\\ \\3x\le 8-2\\ \\3x\le 6\\ \\x\le 2$

So,

$-0.2\le x\le 2$

10. Solve for x:

$8$

Add 1:

$8+1$

Divide by 3:

$3< x\le 4$

Those events are dependent. Once you take out a DVD, you don't put it back, which means for the second DVD, there are less dvd's than there were you took the first one, meaning that there is a greater chance of you getting a specific DVD for your second one.
