In a right triangle, the side adjacent angle a is 12, the
hypotenuse is 24. what is the tangent of the angle a?

Step-by-step explanation:

In a right triangle, the side adjacent angle a is 12, the

hypotenuse is 24.

Angle 'a' is 12

hypotenuse is 24

opposite side = 24 times sin(12)=5

adjacent side = 24 times cos(12)=23.5

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
