Answer:<em> 20 degrees</em>
Step-by-step explanation:
Find the 180 (degrees angle)= angle CD
180 degrees-110 degrees= 70 degrees
By using the OAT (opposite angle theorem), the opposite of the angle OD (you know what i mean) will be 70 degrees too. So, Angle BO is 70 degrees too. We know the right angle there is 90 degrees because of the square sign so, create another 180 degrees angle but subtract 160 degrees (70+90) from 180 degrees which is 20 degrees.

Answer:
2587mm^3 approx!
Step-by-step explanation:
first you divide the nut into 6 part(in triangle now, by joining centre to each edge)
let's take one part of the triangular shape then area of that part can be found by using 1/2×base×height
i.e, 1/2×13×15=97.5(mm^2)
now when we consider depth of that traingular part,we will get volume of that part as area×depth
i.e, 97.5×6=585(mm^3)
now volume of all the 6 triangular part is 585×6=3510(in mm^3)
now take circular cavity in consideration, it's volume will be π(7^2)6=923(mm^3) approximately
now reqired volume will be volume of that hexagonal part minus that of circular cavity
=3510-923
=2587mm^3
