Answer:
115°
Step-by-step explanation:
1. Calculate the value of x
2. Calculate m∠NFE
m∠NFE = 14x + 3 = 14(8) + 3 = 112 + 3 = 115
Answer:
The solution set is: x>36
Step-by-step explanation:
We are given that we have to subtract 3 times of some number 'x' from 18 such that the resulting equation is less than -90.
this means that : 18-3x<-90
on solving the inequality by adding 3x on both side and adding 90 on both side we get that
108<3x
now on dividing both side by 3 we get that
x>36
Hence our solution set is: x>36
