For the differentiable function f, the line tangent to the graph of f at x = has equation, y=3-4(x-1), and the line tangent to the graph off at x = 3 has equation y=2-5(x-3). The differentiable function g is defined by g(x) = f(x) for all x. What is the value of g' (3) ?

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11

i hope it is the answer and it will you..
