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:
8.75
Step-by-step explanation:
first u will find out how mutch he wants he wants 1/2 so u will divide 2.50 by 2 and get 1.25. then you will do 10.00
-1.25
---------
8.75
i hope this helps ;)
690 because 86 is rounded up to 90
the answer is 10.6875 you divide 4. 75 and the number 100 them multiply your answer by 225
glad to help any time
764 divided by 4 is
141
4 can go into 7 once with the remander of 1 then u bring down ur 6 and it gives u 16. 4 can go into 16 4 times without any remanders and thenu are left with 4. 4 goes into 4 one time and then u get the answer 141
