Answer:
2 root 2
Step-by-step explanation:
the cube diagonal of the pyramid inside it makes a triangle.which is a right triangle.and a cub always makes a 45 45 90 triangle so the side with 2 yd is a and the other side is also a so that is also 2 yards and the slant or diagonal is a root 2 so the diagonal is 2 root 2.
Answer:
(- 5, - 2 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (y, - x ), thus
(2, - 5 ) → (- 5, - 2 )
10 = a
24 = b
30 = c
If a^2 + b^2 = C^2 , the triangle is right
if a ^2 + b^2 > C^2 , the triangle is acute
if a ^2 + b^2 < c^2, the triangle is obtuse
since 100 + 576 < 900 , the triangle is : D. Obtuse

Answer:
≈ 18.3 m²
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of sector - area of right triangle
area of sector = area of circle × fraction of circle
A = πr² ×
= π × 8² × = 64π × = 16π m²
area of triangle = × 8 × 8 = 4 × 8 = 32 m²
shaded area is then
A = 16π - 32 ≈ 18.3 m² ( to the nearest tenth )
