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

ABC is isosceles. m X = [?] please help!!

Rashid [163]

Answer:

x = 4

Step-by-step explanation:

The base angles of an isosceles triangle are congruent, as shown in the figure.

Equating their measures, we have ...

∠A = ∠C

8x -7 = 25 . . . . substitute the given expressions

8x = 32 . . . . . add 7

x = 4 . . . . . . divide by 8
