Answer:
b = 87°
Step-by-step explanation:
In order to answer this question, we need to utilise an important angle fact which is <em>angles in a quadrilateral add up to 360° </em>
Using the information we can set up an equation to find the value of b
→ Form equation
63 + 140 + 70 + b = 360
→ Simplify
273 + b = 360
→ Minus 273 from both sides isolate b
b = 87°

Given:
Hexagonal pyramid
To find:
The edges of an hexagonal pyramid.
Solution:
Edges means lines which connecting to vertices.
Edges in the base of the pyramid:
AB, BC, CD, DE, EF, FA
Edges in the triangular shape of the pyramid:
AG, BG, CG, DG, EG, FG
Therefore edges of an hexagonal pyramid are:
AB, BC, CD, DE, EF, FA, AG, BG, CG, DG, EG, FG
