The answer is x = 4, y = -1 or (4, -1).
We are given :
- <u>2x + 7y = 1</u>
- <u>3x + 4y = 8</u>
<u />
Multiply the 1st equation with 3 and 2nd equation with 2.
<u>3. 3(2x + 7y) = 3(1) ⇒ 6x + 21y = 3</u>
<u>4. 2(3x + 4y) = 2(8) ⇒ 6x + 8y = 16</u>
<u />
Now, subtract : Equation 3 - Equation 4.
- 6x + 21y - 6x - 8y = 3 - 16
- 13y = -13
- y = -1
Substitute in the 1st equation.
- 3x + 4(-1) = 8
- 3x - 4 = 8
- 3x = 12
- x = 4

Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem
△FEG is similar with △FHJ -----> by AA Similarity Theorem
so
we have
substitute the given values
I Might know what your talking about. . . .if so then it is A) 40 degrees
