To solve for \( x \) using the angles given, we first need to identify the relationship between the angles.
Assuming that angles ∠1 and ∠4 are supplementary (i.e., they add up to 180°), we can set up the equation as follows:
\[ m∠1 + m∠4 = 180° \]
Substituting the values into this equation:
\[ 125° + (x + 35)° = 180° \]
Now, we can simplify and solve for \( x \):
\[ 125 + x + 35 = 180 \]
Combining the constants on the left side gives:
\[ x + 160 = 180 \]
Subtracting 160 from both sides yields:
\[ x = 20 \]
So, the equation to solve for \( x \) can be expressed as:
\[ x + 160 = 180 \]
Hence, filling in the blanks in the given format, we have:
\( x° + 160° = 180° \)
Thus, the final answer is:
- \( x° + 160° = 180° \)
- \( ° \) = \( 180° \)
