question 5
solve for x.

Explanation:

Step1: Use exterior - angle property

The exterior - angle of a triangle is equal to the sum of the two non - adjacent interior angles. So, $(x + 3)+(x + 4)=127$.

Step2: Combine like terms

$x+x+3 + 4=127$, which simplifies to $2x+7 = 127$.

Step3: Isolate the variable term

Subtract 7 from both sides: $2x=127 - 7$, so $2x=120$.

Step4: Solve for x

Divide both sides by 2: $x=\frac{120}{2}=60$.

Answer:

$60$
