Answer:
7.5 or 15/2 (Whatever form you need to use)
Step-by-step explanation:
N-5 divided by 2 =5
Combine like terms:
-5 divided by 2= -2.5.
N-2.5=5
Add -2.5 from itself, then do the same to the other side:
N-2.5=5
+2.5=+2.5 (Adding 2.5 to -2.5 cancels it out)
N=7.5
Answer:
Step-by-step explanation:
If we are given angles B and C, then all we have to do is add them together and then subtract that from 180 since all the angles of a triangle have to add up to equal 180.
62 + 48 = 110
180 - 110 = 70
Angle A = 70°
