If sin (A+B)=1 and tan (A-B)=1/sqroot 3<br><br> are acute angles. find out the value of A and B​
Nataliya [291]

Answer:

A = 60° , B = 30°

Step-by-step explanation:

sin(A+B ) = 1\\\\\  \  \ (A + B) \  = \ \ sin^{-1} 1\\\\A + B = 90^\circ  --(1)\\\\ \ tan (A - B) = \frac{1}{\sqrt{3}}\\\\(A-B) = tan^{-1}\frac{1}{\sqrt3}}\\\\A - B =  30^\circ --(2)\\\\ (1)  + (2) => 2A = 120^\circ\\

                   A = 60^\circ

from \ (1) \\A + B = 90^\circ\\60^\circ + B = 90^\circ\\B = 90^\circ - 60^\circ\\B = 30^\circ

Which rule deacribes the
Marysya12 [62]

Answer:

A. {T_{-6,-2}}\circ {r_{x-axis}}(x,y)

Step-by-step explanation:

We have that, ΔABC is transformed to get ΔA''B''C''.

We see that the following transformations are applied:

1. Reflection across x-axis i.e. flipped across x-axis.

Now, ΔABC is reflected across x-axis along the line AC to get ΔA'B'C'.

2. Translated 2 units down i.e. shifted 2 units down and and then translated 6 units to the left i.e. shifted 6 units to the left.

So, ΔA'B'C' is translated 2 units downwards and 6 units to the left to get ΔA''B''C''.

Hence, the sequence of transformations is Reflection across x-axis and then Translation of 2 units down and 6 units left.
