Similar triangles are triangles with lengths in proportion, and congruent corresponding angles. When naming a similar triangle, the letters or vertexes are listed in a certain order. For instance, angle X is the same as angle Y so those two letters have to be in the same position. In this case, they are both the first letters. Angle B is congruent to angle N and angle R is congruent to angle J so they will also have to be in corresponding positions. The side lengths are extraneous information that can be used to check, but otherwise I would just stick with angles. Hope this helps!

Can someone answer this question please?

The solution to the inequality $3x-3\leq -15\,\,or\,\,4x-1\geq 11$ is $x\leq -3\,\,or\,\,x\geq 4$

The number line is shown in figure attached.

Step-by-step explanation:

We need to solve the inequality: $3x-3\leq -15\,\,or\,\,4x-1\geq 11$

Solving the inequality:

$3x-3\leq -15\,\,or\,\,4x-1\geq 11\\Adding\,\,3\,\,on\,\,both\,\,sides\,\,and\,\,1\,\,on\,\,both\,\,sides\\3x-3+3\leq -15+3\,\,or\,\,4x-1+1\geq 11+1\\3x\leq -12\,\,or\,\,4x\geq 12$

Divide by 3 and divide by 12

$x\leq \frac{-12}{3} \,\,or\,\,x\geq \frac{12}{4} \\x\leq -4\,\,or\,\,x\geq 3$

So, value of x can be less than equal to -4 or value of x is greater than equal to 3.

The number line is shown in figure attached.

The solution to the inequality $3x-3\leq -15\,\,or\,\,4x-1\geq 11$ is $x\leq -3\,\,or\,\,x\geq 4$
