Find sin(a+B)

diamong [38]

Answer:

Cos A=5/13

we have

Cos² A= $1-Sin ²A$

25/169=1-Sin²A

sin²A=1-25/169

sin²A=144/169

Sin A= $\sqrt{144/169}=12/13$

again

Tan B=4/3

P/b=4/3

p=4

b=3

h= $\sqrt{3²+4²}=5$

Now

Sin B=p/h=4/5

in IV quadrant sin angle is negative so

Sin B=-4/5

CosB=b/h=3/5

Now

Sin(A+B):sinAcosB+CosAsinB

now 

substitute value

Sin(A+B):12/13*3/5+5/13*(-4/5)=36/65-4/13

=16/65 is a required answer

Find the sum and the product of the roots of the equation: x^2−37x+27=0

lawyer [7]

Answer:

Sum of the Roots = 37

Product of the Roots = 27

Step-by-step explanation:

Here, the given expression is $x^{2} - 37x + 27 = 0$

Now the general Quadratic Equation is of the form:

$ax^{2} + bx + c = 0$

Here, Sum of the Roots = $-(\frac{b}{a} )$

and the Product of the Roots = $(\frac{c}{a} )$

So, comparing the general equation with the given equation, we get:

a = 1, b = -37 and c = 27

So, Sum of the Roots = $-(\frac{-37}{1} )$ = 37

and the Product of the Roots = $(\frac{27}{1} )$ = 27
