Answer:

115°

Step-by-step explanation:

1. Calculate the value of x

\begin{array}{rcc}m\angle GFM + m\angle NFE & = & m\angle GFE\\4x + 10 + 14x + 3 & = & 157\\18x + 13 & = & 157\\18x & = & 144\\x & = & \dfrac{144}{18}\\ & = & 8\\\end{array}

2. Calculate m∠NFE

m∠NFE = 14x + 3 = 14(8) + 3 = 112 + 3 = 115

Answer:

\large\boxed{16x^2-24x+9=(4x-3)^2}

Step-by-step explanation:

\text{Perfect square:}\ (a-b)^2=a^2-2ab+b^2\\=======================\\\\25x^2-20x-16\to\text{NOT. Because is}\ -16=-4^2\\\\9a^2-30a-25\to\text{NOT. Because is}\ -25=-5^2\\\\25b^2-15b+9=(5b)^2-2(5b)\left(\dfrac{3}{2}\right)+3^2\to\text{NOT. Because is}\ b=\dfrac{3}{2}\ \text{and}\ b^2=3^2\\\\16x^2-24x+9=(4x)^2-2(4x)(3)+3^2=(4x-3)^2\ \boxed{YES\ :)}
