RS =7a,ST = 12a, RT = 76

in a triangle ABC
PQ II BC
P be the mid point of side AB and Q be the mid point of AC
then prove that area of triangle OBC=area of rectangle OPAQ

[note-- QB and PC are crossing lines inside the triangle and they meet at a point O which lies inside the
triangle

P is a point inthe interiour of a rectangle ABCD.if P is joined to each of the vertices of the rectangle and the lengths of PA ,PB and PC are 3cm,4cm and 5cm respectively prove that PA2+PC2=PB2+PD2 and find the length of CE

find the perimeter of a rhombus if the diagonal are 6cm and 8 cm

hello

i have many objects with known centre of mass coordinates distributed on a plane.
the objects have 2 main shapes (cudic and cylindrical).

i previously calculated the distance between there centres of mass to detect if they intersect 2 by 2.

now all what i need is to know which object is visible to the others so i can calculate the view factor
related to each object with respect to only the visible onces.

I'm waiting your help. thank's

your town purchases a new fire truck with a 100ft extension ladder. About how close can the fire truck come to a building when the ladder is fully extended at an angle of 60 degrees? The ladder extends from the top of the truck, 8 ft up. About how high up the building does the ladder reach?

how much grain will a silo hold if the height of a ladder is 40 feet and the radius is 6 ft

Is a right.triangle can be isosceles triangle?

The silo on a farm is a composite figure. What two shapes make up the Silo? Choose an answer from below.

A. Prism and Sphere B. Prism and Hemisphere
C. Cylinder and Sphere D. Cylinder and Hemisphere


To the nearest pound, how much grain with the Silo hold if the height of the ladder is 40 feet and the radius is 6 feet? (1 cubic foot = 62.43 pounds)
