Answer 1

Question:

Solution:

Remember that there are five ways to find if two triangles are congruent. One of them is SAS (side, angle, side). According to this, we get the following equation:

`2x\text{ - 26 = x +16}`

now, putting together similar terms we obtain:

`2x\text{ - x = 16 +26}`

this is equivalent to:

`x\text{ = 42}`

so that, we can conclude that the correct answer is:

`\text{ 42}^(\circ)`
