16x^2+1=y would be the inverse of y=16x^2+1
- 84.7 + 59.2, this is your expression
=3/2+ 9/4+ 2/2
=1.5+ 2.25+ 1
=4.75
Hey there!
To find the value of an angle in a triangle, you need to add the 3 angles. You have angles with 55 degrees, 65 degrees, and x degrees. Put this into an equation. The equation would be 55+65+x=180. Simplify to get 120+x=180. You need to isolate x, so subtract 120 from both sides to get x=60. So the value of x is 60 degrees.
I hope this helps!
