Question

the two labeled angles are complementary angles. that means that their measures sum to 90°. use the relationship you determined to write an equation to help you solve for x. 8x - 13 + 39 = 90 add to both sides :add what to both sides? 8x + 26 + \square = 90 + \square

Explanation:

Step1: Simplify the left side

First, simplify \(8x - 13 + 39\). Combine the constant terms: \(-13 + 39 = 26\), so the equation becomes \(8x + 26 = 90\).

Step2: Isolate the term with x

To isolate \(8x\), we need to subtract 26 from both sides (or add \(-26\) to both sides). So we add \(-26\) to both sides of the equation \(8x + 26 = 90\).

Answer:

The blanks should be filled with \(-26\) and \(-26\) respectively. So the equation is \(8x + 26 + (-26)= 90 + (-26)\)
