The sum of the complementary angles always is 90°.
Therefore:
![x+(14x+15)=90](https://img.qammunity.org/2023/formulas/mathematics/college/olsfh80fb4uxpgw7wo8l68m2tiwzejduxa.png)
Solving for x:
![\begin{gathered} x+(14x+15)=90 \\ x+14x+15=90 \\ 15x+15=90 \\ 15x=90-15 \\ x=(75)/(15)=5 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ig0fiz4bamz36mi5cse3bkc2wvhacweks9.png)
Now, we know that x is equal to 5. Finally, putting x=5, we get:
angle1. x=5°.
angle2= 14x+15= 14*5+15= 85°.
Answer: The measure of x° is 5° and the mesure of (14x + 15)° is 85°.
