solve for the value of k.

answer attempt 1 out of 2
k =

Explanation:

Step1: Set up angle sum equation

The three angles form a right angle ($90^\circ$), so:
$$(9k+8) + 73 = 90$$

Step2: Simplify the left side

Combine constant terms:
$$9k + 81 = 90$$

Step3: Isolate the variable term

Subtract 81 from both sides:
$$9k = 90 - 81$$
$$9k = 9$$

Step4: Solve for k

Divide both sides by 9:
$$k = \frac{9}{9}$$

Answer:

$k = 1$
