Step-by-step explanation:
I found the value of x to be 6 by adding the two equations together and setting them equal to 180.
2x^2+3x-5+x^2+11x-7=180
When you solve for x you get x=6
Then you plug 6 in for x in each angle. The first angle is 85 and the second is 95.
For this question u can use a^2+b^2=c^2!
6^2+10^2=c^2
u will get 2✓34
