.

Hence, the correct option is
.
1- ASA for all triangle mentioned. The have one side adjacent to 2 angles
z=(63-84)/3= -21/7= -3
P(x>63)=p(z > -3) = .9987 or 99.87%
Answer:
Equation: 
Solve for n: n = 112
Step-by-step explanation:
To first set up the equation, you need to look at the verbal description and translate into numbers and operations:
'three fourths a number' = 
'plus 8' = + 8
'is' =
'20 less' = - 20
'the number' = n
Put the expressions together:
'three fourths a number plus 8': 
'20 less than the number': n - 20
Set them equal to each other and solve: 
Add 20 to both sides: 
Subtract
from both sides: 
Multiply both sides by
: 
Solve for n: n = 112
