Answer:
25/332
Step-by-step explanation:
In all right triangles, the ratio between a leg and the hypothenuse is the sine of the angle opposite to the leg.
So, in your case, we have
![\sin(Z) = \dfrac{XY}{XZ}](https://tex.z-dn.net/?f=%5Csin%28Z%29%20%3D%20%5Cdfrac%7BXY%7D%7BXZ%7D)
In order to find XY, we have
![XY = \sqrt{XZ^2-YZ^2} = \sqrt{1600-1024}=\sqrt{576} = 24](https://tex.z-dn.net/?f=XY%20%3D%20%5Csqrt%7BXZ%5E2-YZ%5E2%7D%20%3D%20%5Csqrt%7B1600-1024%7D%3D%5Csqrt%7B576%7D%20%3D%2024)
So, the ratio for the sine is
![\sin(Z) = \dfrac{XY}{XZ} = \dfrac{24}{40} = \dfrac{3}{5}](https://tex.z-dn.net/?f=%5Csin%28Z%29%20%3D%20%5Cdfrac%7BXY%7D%7BXZ%7D%20%3D%20%5Cdfrac%7B24%7D%7B40%7D%20%3D%20%5Cdfrac%7B3%7D%7B5%7D)
Step-by-step explanation:
from what I can see there are 2 options to make the 2 triangles congruent :
either the opposite sides must be equal or the neighboring sides must be equal.
so, either
5x = 3x + 10
and
5x - 2 = 4x + 3
or
5x = 4x + 3
and
5x - 2 = 3x + 10
for the first
5x = 3x + 10
2x = 10
x = 5
control
5x - 2 = 4w + 3
5×5 - 2 = 4×5 + 3
23 = 23
correct.
for the second
5x = 4x + 3
x = 3
control
5×3 - 2 = 3×3 + 10
15 - 2 = 9 + 10
13 = 19
no, not a valid solution.
so, x = 5
