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

Your new dresser will be 2/5ths larger than your old dresser. Your old dresser can hold 6.25 cubic feet, how much cubic feet wil

marissa [1.9K]

Answer:

8.75 cubic feet

Step-by-step explanation:

Your new dresser will be $\frac{2}{5}^{ths}$ larger than your old dresser.

This means that your new dresser wil be

$1+\dfrac{2}{5}=\dfrac{5+2}{5}=\dfrac{7}{5}$

of your old dresser.

Your old dresser can hold 6.25 cubic feet, so your new dresser can hold

$\dfrac{7}{5}\cdot 6.25=7\cdot 1.25=8.75\ ft^3$
