If triangle rst is an acute triangle, then m∠s must be

less than 90°.
equal to 90°.
equal to 100°.
greater than 90° and less than 180°.

m ∠ S must be less than 90°

Therefore; if triangle RST is an acute triangle; then;

∠R , ∠S and ∠T, all are less than 90.

answer: what in the world is this

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
