Candice is going to replace the top of a table with a new piece of wood. How many square feet of wood would she purchase? 8ft. , 5 ft , 12 ft

She  needs to purchase  50  square feet of wood .

Step-by-step explanation:

we can find the number of square feet of wood needed to purchase by finding the area of the table

The area of the table  =  area of the triangle + area of the rectangle

Area of the triangle:

Area of the triangle  =

On substituting the values from the attached figure , we get

Area of the triangle  =

Area of the triangle  =

Area of the triangle  = 10 square feet

Area of the rectangle:

Area of the rectangle = Length X  Breadth

On substituting the values from the attached figure , we get

Area of the triangle  =

Area of the triangle  =  40 square feet

Thus the area of the table  = 10 +  40 = 50  square feet

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
