$\large\color{lime}\boxed{\colorbox{black}{Answer : - }}$

We know that, in ∆ABC,

∠A+∠B+∠C = 180°

But the triangle is right angled at C

ie., ∠C = 90°

Therefore, ∠A+∠B+ 90° = 180°

⇒ ∠A + ∠B = 90°

Therefore, cos(A + B) = cos 90º = 0

Answer:

$x^{3} -5x^{2} -6x +8 \frac{-2}{x + 3}$

Step-by-step explanation:

$x^{3} -5x^{2} -6x +8 \frac{-2}{x + 3}$

x + 3 / $x^{4} - 2x^{3}-21x^{2} -10x +22$

-( $x^{4} + 3x^{3}$ )

- $5x^{3} -21x^{2} -10x +22$

-( $-5x^{3} -15x^{2}$ )

$-6x^{2} -10x +22$

-( $-6x^{2} -18x$ )

8x +22

-(8x + 24)

$\frac{-2}{x + 3}$

40.32 is 76.8% of what number?

julsineya [31]

Hey there

Lets solve this question together,

Convert 76.8% to a decimal.

$0.768 * x=40.32$

Multiply 0.768 by x to get 0.768x.

$
0.768x=40.32$

Multiply each term by 1 / 0.768 and simplify.

Cancel the common factor of 0.768.

$x=40.32 / 0.768$

Divide 40.32 by 0.768 to get 52.5

 $x=52.5$
