In the image you uploaded, there is an angle labeled as 35°, and an unknown angle marked as (5n)°. It appears that you are trying to find the unknown angle, likely using the relationship between the two angles.

Based on the diagram, it seems that the angles are on a straight line, which means they are supplementary angles. The sum of supplementary angles is always 180°.

Let's set up the equation:

$35° + 5n = 180°$

To solve for $n$:

1. Subtract 35 from both sides: $5n = 180° - 35° = 145°$

2. Divide both sides by 5: $n = \frac{145°}{5} = 29°$

So, $n = 29°$, and the unknown angle is: $5n = 5 \times 29° = 145°$

Therefore, the unknown angle measures 145°.
