Answer:
x=pi*n/2+1/2arctan(7/5)
Step-by-step explanation:
5sin(2x)=7cos(2x)
5tan(2x)=7/5
2x=pi*n+arctan(7/5)
x=pi*n/2+1/2arctan(7/5) for n e Z
Answer:
she used her fingers to guess the inches
Step-by-step explanation:
The answer is D. The last choice
-28 = 22 - 5x
-28 -22 = 22 -22 -5x
-50 = -5x
-50/-5 = -5x/-5
10 = x
x = 10
