The ratio for questions number 2 is C aka 3 to 5
The little lines through the two sides of the triangle mean the sides are equal length.
Because the sides are equal, the two bottom angles are also the same.
Since angle B is given as 46 degrees, angle C is also 46 degrees.
The three inside angles of a triangle need to equal 180 degrees.
Angle A = 180 - 46 - 46 = 88 degrees.
Answer:
34 edges
Step-by-step explanation:
Euler's formula for polyhedron states
F + V - E = 2
where F is number of faces, V, number of vertices, E number of edges
Here F = 16, V = 20, thus
16 + 20 - E = 2, that is
36 - E = 2 ( subtract 36 from both sides )
- E = - 34 ( multiply both sides by - 1 )
E = 34
