I hope this helps you



✔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

Can anyone help me find the value please?
AURORKA [14]

Answer:

the answer is x=15 cm

Step-by-step explanation:

here the above given figure is a rectangle ABCD with diagonals AC and BD measuring AC= (x+10)cm and BD=(3x-20) cm

Now,

AC=BD

or, 3x-20 = x+10 [ diagonals of a rectangle are equal]

or, 2x = 30

or, x= 15 cm

I HOPE IT WILL HELP YOU!!!

If 2+root3/2-root/3 + 2-root3/2+root3 =a+b root3 find the values of a and b
andreyandreev [35.5K]
To solve for 2 variables, you need 2 equations. The best you could do with only one equation would be to find 'a' in terms of 'b'. Just looking it over and without putting pen to paper, it looks to me like one possible solution is [ a = 4, b = 0 ].
