Answer 1

b = 8 degrees

The sum of the three angles of any triangle is equal to 180 degrees.

`\begin{gathered} 15b-26+5b+46=180^0(sum\text{ of angle in a triangle)} \\ \text{seperate similar terms} \\ 15b+5b+46-26=180^0 \\ 20b+20=180^0 \\ \\ \text{seperate similar terms} \\ 20b=180-20 \\ 20b=160 \\ \text{divide both sides by 20} \\ (20b)/(20)=(160)/(20) \\ \\ b=8^0 \end{gathered}`
