the answers A
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
Just plug "F=122" into the formula,
C = 5*(122-32) / 9
C = 5*(90) / 9
C = 50
Answer:
115, 65
Step-by-step explanation:
Let x be an angle measurement
x-50 is the supplement
They add to 180
x + x-50 = 180
2x-50 = 180
Add 50 to each side
2x-50 + 50 =180+50
2x = 230
Divide by 2
2x/2 =230/2
x = 115
The measure are 115 and 115-50=65
