A triangle has a total degrees of 180, so you add 55 and 53 to get 108
then you subtract that from 180 to get 72. 72 is your answer
We know the sum of the angles in a triangle is 180°. We also know what two of the angles in this triangle are. Using this we can calculate the third angle to be 180-73-51= 56°. We now know that x+21= 56 subtracting 21 from both sides we get x= 35°
2.16 is not the same as 2 1/6
Tabitha's error was that she just wrote 2 1/6 without converting it correctly.
Answer:
b[c(t)] = 420t
Step-by-step explanation:
b(c)=1.2c where c(t)=350t
so
b[c(t)]=1.2(350t)
=420 t
