Which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle? the triangle is acute because 22 + 52 > 42. the triangle is acute because 2 + 4 > 5. the triangle is not acute because 22 + 42 < 52. the triangle is not acute because 22 < 42 + 52.

Let

we know that

If -----> is a right triangle

If -----> is an obtuse triangle

If -----> is an acute triangle

so

substitute the values

------> is an obtuse triangle

therefore

the answer is

The triangle is not acute because

answer is more than one

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
