Answer: 16
Step-by-step explanation: 20/2 = 10
10x=160
10x/10=160/10
x=16
Hey there :)
- tan²x + sec²x = 1 or 1 + tan²x = sec²x
sin²x + cos²x = 1
Divide the whole by cos²x


so

and

so

Therefore,
tan²x + 1 = sec²x
Take tan²x to the other side {You will have the same answer}
1 = - tan²x = sec²x or sec²x - tanx = 1
Answer:
The functions share a y intercept of -1
Step-by-step explanation:
Both functions cross the y axis and y=-1 and x=0
They both have the same y intercept
