✔cos^2A+sin^2A=1
✔1-cos^2A=sin^2A
✔cos2A=cos^2A-sin^2A
✔sin2A=2.sinA.cosA
secA=1/cosA
tgA=sinA/cosA
sin^2A/1/cos^2A-sin^2A/cos^2A
sin^2A.cos^2A/cos2A
2.sin^2A.cos^2A/cos2A
sin2A.2.sin2A/cos2A
tg2A.2.sin2A
The answer is x=7/3 hope this helps
Answer:
Its value is 10.
Step-by-step explanation:
Use order of operations, PEMDAS.
The parentheses are worked out first:-
(5 - 3) X 2 + 6
= 2 X 2 + 6
Now the multiplication:-
= 4 + 6
= 10 (answer).
Combine (subtract) 3n and 2n to get 1n or n. Then you have n -5n =10n add 5n to 10n to get 15n. divide the 15 from n and your answer is n=15
