there are atleast 4 pair of parallel faces shown
32. p is 3r-1. (3r-1)+r=43. 4r-1=43. 4r=44. r=11. p=3r-1. p=3(11)-1. p=32.
Answer:
x = 8
m∠BOC = 37°
m∠AOB = 53°
Step-by-step explanation:
If OA is perpendicular to OC, this means that <AOC = 90°
Given
m∠BOC=6x−6
m ∠AOB = 5 x + 8
The expression is true
m∠BOC+m∠AOB= m∠AOC
6x-6+5x+8 = 90
Find x:
11x + 2 = 90
11x = 90-2
11x = 88
x = 88/11
x =8
Get m∠BOC:
m∠BOC= 6x-6
m∠BOC= 6(8)-11
m∠BOC = 48-11
m∠BOC= 37°
Get m∠AOB;
m∠AOB = 90-m∠BOC
m∠AOB =90-37
m∠AOB = 53°
