Question

I need to know if A and B are correct and I need HELP WITH C

Answer 1

(a) In the given triangle,

$\begin{gathered} 53\text{ + 68 + x = 180 \_\_\_\_\_\_\_( Angle sum property )} \\ 121\text{ + x = 180 } \\ x\text{ = 180 - 121} \\ \text{x = 59} \end{gathered}$

(b) In the given triangle,

$\begin{gathered} 71\text{ + 46 + x + 180 \_\_\_\_\_\_\_( Angle sum property )} \\ 117\text{ + x = 180} \\ x\text{ = 180 - 117 } \\ x\text{ = 63} \end{gathered}$

(c) In the given triangle,

$\begin{gathered} x\text{ + x + }24\text{ = 180 \_\_\_\_\_\_\_\_( Angle sum property )} \\ 2x\text{ + 24 = 180 } \\ x=\frac{180-24}{2} \\ x\text{ = 78} \end{gathered}$
