x ≈ 54.8°

Using the tangent ratio in the right triangle

tan x = $\frac{opposite}{adjacent}$ = $\frac{PQ}{QR}$ = $\frac{7.1}{5}$ , then

x = $tan^{-1}$ ( $\frac{7.1}{5}$ ) ≈ 54.8° ( to the nearest tenth )

Anestetic [448]

(2/5)(x-1)<(3/5)(x+1) perform indicated multiplications

(2x-2)/5<(3x+3)/5 multiply both sides by 5

2x-2<3x+3 add 2 to both sides

2x<3x+5 subtract 3x from both sides

-x<5 divide both sides by -1 (remember to reverse direction of inequality sign when multiplying/dividing by a negative value)

x>-5
