Answer:

Step-by-step explanation:

The triangles are congruent because they are the same shape, size, and angle measure. The lines on the angles show that two angles have the same measure. The line on the line segments shows that it hads the same length.

Answer:

(3l + (3)1.25) + 2m = 52.50

Step-by-step explanation:

(3l + (3)1.25) + 2m = 52.50

3*9.75 + 3.75 + 2*9.75

(29.25 + 3.75) + 19.50

33.00 + 19.50 = 52.50

Derive Sinxy = x² + 2xy

bogdanovich [222]

Answer:

$\frac{dy}{dx} = \frac{2x +2 y- ycosxy}{x(cosxy-2)}$

Step-by-step explanation:

Step(i):-

Given

sin xy = x² + 2xy ...(i)

Apply

$\frac{d}{dx} UV = U^{l} V + U V^{l}$

$\frac{d}{dx} x^{n} = nx^{n-1}$

Differentiating equation (i) with respective to 'x', we get

$cosxy \frac{d}{dx} (xy) = 2x + 2( x\frac{dy}{dx} + y(1))$

$cosxy (x\frac{dy}{dx} +y(1)) = 2x + 2( x\frac{dy}{dx} + y(1))$

$cosxy (x\frac{dy}{dx}) + ycosxy = 2x + 2( x\frac{dy}{dx}) +2 y)$

$cosxy (x\frac{dy}{dx}) - 2( x\frac{dy}{dx}) = 2x +2 y- ycosxy$

$(cosxy-2) (x\frac{dy}{dx}) = 2x +2 y- ycosxy$

$\frac{dy}{dx} = \frac{2x +2 y- ycosxy}{x(cosxy-2)}$
