Question 108254This question is from textbook Geometry for enjoyment and challenge

: Given: triangle NEW is congruent to triangle CAR, EN = 11, AR = 2x-4y, NW = x+y, CA = 4x+y, EW = 10.
Find CR
I'm thinking this is really an algebraic problem: 2x-4y = 10 and 4x+y =11. If I can find the value of the variables, I can find CR. Is this correct? If so, how do I solve this algebra problem?
Page number 164 in the textbook.

Question 112080: This problem includes triangles, but is presented as a pre-calculus problem. Since I cannot upload the triangle I'll describe it. Triangle ABC is made up of two triangles. The smaller triangle is a 45,45,90 and it's height is 7. The second triangle is larger and is a 30,60,90 it's height is also 7. I found the hypotenuse and base for the 45,45,90 triangle they are: hypotenuse= 7 square roots of 2 and base= 7. I am having trouble finding the hypotenuse and base of the 30,60,90 triangle. How do I solve for this?
Thank you so very much for your time.
