The intersecting secant-tangent theorem says that

where T is the point at which line segment PO touches the circle. Similarly,

so we have

OP is of course as long as itself, and AO and BO are radii of the same circle so they have the same lengths.
This means triangles APO and BPO are congruent, which means angles APO and BPO are congruent, so angle APB is bisected by PO.
For a cuboid's volume you simply go length x width x heigth so 2x4x5 so it's 40.
Answer:
Your answer is 7
Hope this helps!
Step-by-step explanation:
You plug 14 in for x then just do 14-7 and you will get 7
