Volume = Area of triangle x length
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 5 x 4
Area of triangle = 10
Volume = area of triangle x length
Volume = 10 x 12
Volume = 120 cm^3
p^2+6p+9=0

Answer:
17degrees
Step-by-step explanation:
Since the triangle ABC is a right angled triangle, one of the angle is 90 degrees
The sum of angle in a triangle is 180
m<A + m<B + m<C = 180
73 + 90 +m<C = 180
163 +m<C = 180
m<C = 180-163
m<C = 17 degrees
Hence the third angle is 17degrees
Answer:
The total surface area of the square pyramid is
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to the area of the square base plus the area of four triangular faces
so
