Question

What is the value of x? A. 33 B. 47 C. 28 D. 43 don’t have much time please help

Answer 1

A. 33

Step-by-step explanation

By the angle addition theorem, the sum of all these angle measures is 180º:

`104+(x)+(x+10)=180`

Solving for x:

`\begin{gathered} 104+x+x+10=180 \\ 104+2x+10=180 \\ 2x+114=180 \\ 2x=180-114 \\ 2x=66 \\ x=(66)/(2) \\ x=33 \end{gathered}`
