The angles ∠ABC and ∠CBE together should equal 180º.
∠ABC is 155º.
180 - 155 = 25
So, ∠CBE = 25º.
Hope this helps!
To find the surface are of the base: 8 * 8 = 64/2(becasue its a triangle not a square base) = 32.
To find the surface are of the 3 other faces, 12 * 8 = 96/2 = 48 * 3(for the 3 sides) = 144.
The entire surface area is 176.
1. 2.22
2. 4.95
For the 4 you devide 50 by 6 and for 5 you subtract
