I needdd helpppppp what is m<2+m<3?

Leviafan [203]

In triangle ABC:

∠1 = 90°

According to the angle sum property:

∠1 + ∠2 + ∠3 = 180

Since angle 1 is 90 degrees

∠2 + ∠3 = 180 - 90

∠2 + ∠3 = 90° [∠1 + ∠2 + ∠3 = 180]

What is the value of (tan 65° - tan 35°) / 1 + tan 65°tan 35°? 0 0 V3/3

goldenfox [79]

Answer:

$\frac{ \sqrt{3} }{3}$

Step-by-step explanation:

We know that tangent angle addition formula is

$\tan(a - b) = \frac{ \tan(a) - \tan(b) }{1 + \tan(a) \tan(b) }$

This is in form already. Based on the value, a is 65 and b is 35 so let just subtract that

$\tan(65 - 35) = \tan(30)$

W e know that tan 30 is

$\tan(30) = \frac{ \sin(30) }{ \cos(30) } = \frac{ \frac{1}{2} }{ \frac{ \sqrt{3} }{2} } = \frac{1}{ \sqrt{3} } = \frac{ \sqrt{3} }{3}$

FIRST CORRECT GETS BRAINLIEST

BARSIC [14]

Answer:

First choice.

Step-by-step explanation:

cos 11π/6 = cos π/6 = √3/2

So cos 11π/12 = √(1 + cos 11π/6) / √2

= √(1 + √3/2) / √2

= √(2 + √3) / 2.

Answer: ‭4,250.52 Rupees

Step-by-step explanation:

If one U.S. dollar was worth 66.79 Indian Rupees, it means that were you to exchange both currencies, a dollar would get you 66.79 Rupees and 66.79 Rupees would get you a Dollar.

If you had $63.64 Dollars therefore, the number of Rupees you could get is the amount of dollars multiplied by the amount of Rupees:

= 63.64 * 66.79

= ‭4,250.52 Rupees
