Question

1. find b.

Explanation:

Step1: Identify angle relationship

The angle \( b \) and the \( 35^\circ \) angle are supplementary (they form a linear pair, so their sum is \( 180^\circ \)).

Step2: Calculate \( b \)

Using the supplementary angle formula: \( b + 35^\circ = 180^\circ \). Solving for \( b \), we get \( b = 180^\circ - 35^\circ \).
\( b = 145^\circ \)

Answer:

\( 145^\circ \)
