Answer:
no
Step-by-step explanation:
The supplementary angle to 69 degrees would be 111 DEGREES.
because it has to add up to 180 (69 + 111 = 180)
Answer:
32 sq. ft.
Step-by-step explanation:
1/2 (8x8)=1/2(64)=32
To find the surface area of the figure , we need to add the surface area of all the faces
So the surface area of figure = Area of two lateral rectangular faces + Area of two triangular faces + area of base
hence
Surface Area of figure = 2(10*15) + 2( 1/2 * 8 * 12) + (12*15)
= 300 + 96 + 180
= 576 square feet
So correct option is the last one
