Question

question 5 (1 point) solve for x. remember to set up your equation. hint. it might seem like a difficult equation, but its really not that challenging. setting up the equation is the key. 7x - 4° 6x - 4° 5x + 8° a 12 b 10 c 180 d 22

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, we set up the equation $(7x - 4)+(6x - 4)+(5x + 8)=180$.

Step2: Combine like - terms

Combine the x - terms and the constant terms: $(7x+6x + 5x)+(-4-4 + 8)=180$. This simplifies to $18x=180$.

Step3: Solve for x

Divide both sides of the equation $18x = 180$ by 18. So, $x=\frac{180}{18}=10$.

Answer:

10
