I think the answer is 2 3/5 and 11/5
Answer:
31.2
Step-by-step explanation:
Because you only round up if the number next to the 1st decimal place is greater than 5, you just drop the 4 and keep 31.2.
Answer:
100 and 80
Step-by-step explanation:
Let x = be the first angle
x-20 is the second angle
They are supplementary so they add to 180
x+x-20 = 180
Combine like terms
2x-20 =180
2x-20+20 =180+20
2x= 200
Divide by 2
2x/2 = 200/2
x= 100
The first angle is 100 and the second is x-20
x-20 = 100-20=80
The two angles are 100 and 80
