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.

what are the statements

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
