[tex] \\ \texttt{area \: of \: a \: triangle: } \: \frac{1}{2} bh \\ [/tex]

Base: x+8

Height: x+5

[tex] \\ \frac{1}{2} (x + 8)(x + 5) \\ [/tex]

Evaluate, change the value x= 2

[tex] \\ \frac{1}{2} (2 + 8)(2 + 5) \\ [/tex]

Add the numbers in the parentheses

[tex] \\ \frac{1}{2} (10)(7) \\ [/tex]

Multiply

[tex] \\ \frac{1}{2} (70) = \boxed{ \green{ \sf{ 35}}} \: \\ \\ \\ [/tex]
