Given this is a right triangle

85^2 = 7225

84^2 = 7056

85^2 - 84^2 = 169 = 13^2

Sin QR / QP = sin 84 / 85 = 81.2 deg

Hi there! :)

$\large\boxed{j(h(x))(2) = 31}$

Solve for j(h(x)):

h(x) = x² + 4

j(x) = 4x - 1

Substitute in h(x) into "x":

j(h(x)) = 4(x² + 4) - 1

j(h(x)) = 4x² + 16 - 1

j(h(x)) = 4x² + 15

Solve at x = 2:

4(2)² + 15 = 4(4) + 15 = 31.
