The box is 12 inches long 8 inches wide and 3 inches high . what is the surface area

to find surface area do the length times the width.

so for this question we would do 3x8=24

Step-by-step explanation:

to get the surface area you need to run this equation    (L*w)*2+(W*H)*2+(L*H)*2

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
