In the diagram, triangle ABC is congruent to triangle DEF.
The values of x and y:
x = 5 in, y = 20°

eq1
7x + y = 55
y = 55 - 7x
eq2
3x - 3 = 12
3x = 12 + 3
3x = 15
x = 5
y = 55 - 7(5) = 20
so
7x + y = 7(5) + 20 = 55° answer//
3x - 3 = 3(5) - 3 = 12 in answer//

Since the triangles are congruent , then AB = DE & angle C = Angle F
12 = 3x - 3 & 55 = 7x + y
Hence 9 = 3x
x = 3
When x = 3
55 = 7(3) + y
55 = 21 + y
y = 34

DE is 12 so x is 5
7 x 5 = 35 55 - 35 = 20 so 7 = 20 I think .
So x = 5 and y = 20 maybe .

If they are congruent, 7x + y = 55 degrees, and
3x - 3 inches = 12 inches
You do the rest.

From diagram with triangle ABC is congruent to triangle DEF
---> ∠C =∠ F
and AB = DE
solve 2 equations for x , y

Surprising how many people get try to get their education on Yahoo! Answers or get
others to do their coursework and then pass it off as their own.
