Answer:
Step-by-step explanation:
Remember that complementary angles <em>always </em>add up to 90°.
We know that the two complementary angles are represented by (x) and (x+14). In other words:
So, let's solve for x.
First, combine like terms:
Let's isolate the x by subtracting 14 from both sides:
The left cancels. Subtract on the right:
Divide both sides by 2:
The left side cancels. Divide on the right:
So, the value of x is 38°.
And we're done!
