We want to find the value of x in the given triangle.
To find the value of x, we will first recall a key piece of information!
Angle Sum of a Triangle
With this rule, we can write an equation connecting the measures of the angles of our triangle. x^(∘)+ 55^(∘)+ 79^(∘)=180^(∘) Let's solve the equation and find the value of x. For simplicity, we will not write the degree symbol.
