Answer: The answers are in the photo.

Step-by-step explanation:

To solve 11, we need to mark the triangle. Since we know that LMN is an isosceles triangle, we can use the iso. triangle theo. proof to mark some angles and sides.The iso. triangle theo. is that an isosceles triangle's opposite base angles are congruent, and the sides opposite of the bases angles are congruent to each other (meaning 2 sides are congruent and 2 angles are congruent.) Since T is the midpoint of LN, LT and TN are congruent. Triangles LMT and LNT also share a same side we can also mark.

To solve number 12, you can use CPCTC- congruent parts of congruent triangles are congruent. Anything in LMT and LNT are congruent to each other, making angles 1 and 2 congruent.

To solve number 13, you just need to place and plug. We know the right base vertice has a y of 0 because it is sitting on the x-axis. Because this triangle is isosceles, we can use the value of the top vertices x, multiply it by 2, which gets 2a as the x of the right base vertice. In the end, it's coordinates are (2a,0).

I apologize if this explanation is sloppy.

What are the coordinates of the vertex of the graph of
vesna_86 [32]
The vertex is (3,0). The 3 inside the abs val bar tells you the x value of the vertex is 3. No number outside the abs value bar is a +0 which is the y value of the vertex.

5 more than the product of 4 and some number is equal to 33
gregori [183]

Answer:

33 = 4x + 5

Step-by-step explanation:

If you convert this expression into numbers, it would be 4 times the number x plus 5 is equal to 33.

Hopefully this helps! Let me know if you have any questions!
