We can use Pythagoras’ theorem for this
Answer:
1109
Step-by-step explanation:
you can subtract the terms to see the difference between them
-11-(-27)=16
The sequence is increasing by 16
you can plug that 16 in the formula for d
a_n=a_1+(n-1)d
a_n=a_1+(n-1)16
n represents the term you want to find in this case the 72nd
a sub 1 is the first term of the sequence in this case -27
a_72=-27+(72-1)16
a_72=-27+(71)16
a_72=-27+1136
a_72=1109
Answer:
TanФ=-1.793
Step-by-step explanation:
![Sin^{2} (A) + Cos^{2} (A) = 1](https://tex.z-dn.net/?f=Sin%5E%7B2%7D%20%28A%29%20%2B%20Cos%5E%7B2%7D%20%28A%29%20%3D%201)

6.4 rounded to the nearest whole number will be 6.
if the decimal was 5 or larger, it would’ve been 7.
