Step-by-step explanation:
So 4x2+9 has no linear factors with Real coefficients. It is possible to factor it with Complex coefficients.
Type it into ur calculator as √175 and if you need radical form it’ll be 5√7 or just 13.2 (13.2287565553)
To determine the measure of angle C. You would solve the equation for X. X+47=180. X= 180-47. X= 133. The measure of angle C is 133 degrees.
