Question

question solve for the value of n.

Explanation:

Step1: Set up equation

Since the two - angle measures sum to 90° (as they form a right - angle), we have the equation $2n+(3n - 5)=90$.

Step2: Combine like terms

Combining the $n$ terms on the left - hand side gives $(2n+3n)-5 = 90$, which simplifies to $5n-5 = 90$.

Step3: Add 5 to both sides

Adding 5 to both sides of the equation $5n-5 = 90$ gives $5n-5 + 5=90 + 5$, so $5n=95$.

Step4: Solve for n

Dividing both sides of the equation $5n=95$ by 5, we get $n=\frac{95}{5}=19$.

Answer:

$n = 19$
