If sin a= 12/13 and tan b 8/15 and angles a and b are in qundrant 1 find the value of tan (a+b)

The value of Tan (a + b) is .

Step-by-step explanation:

Given as :

Tan b =

Sin a =

∵Sin Ф =

So,   =  

Now, Base² = Hypotenuse² -  Perpendicular²

Or, Base² = 13² - 12²

Or,  Base² = 169 - 144

Or,  Base² = 25

∴     Base = = 5

And Tan Ф =  

Or, Tan a =

Now, Tan (a + b) =

Or, Tan (a + b) =

or, Tan (a + b) =

or, Tan (a + b) =

Or, Tan (a + b) =

Hence The value of Tan (a + b) is . Answer

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
