Answer:

a = 39.2650873379cm

b = 11.5529459767cm

Step-by-step explanation:

a - Use the area of a triangle equation - 1/2 * a * b * Sin(C)

1/2 * 8 * 10 * Sin(79) = 39.2650873379cm

b - Use the cosine rule - c^2 = a^2 + b^2 - (2 * a * b * Sin(C)

64 + 100 - (2 * 8 * 10 * Cos(79)) = 133.4705607398

c = square root of 6.9396506484 = 11.5529459767cm

Put to however many significant figures / decimal places required.

Suppose that y varies inversely with x. Given x=-3 when y=-105. Find y when x=15

Allushta [10]

Answer:

Step-by-step explanation:

It is given that y varies inversely with x.

$y\propto \dfrac{1}{x}$

$y=\dfrac{k}{x}$ ...(i)

where, k is constant of proportionality.

It is given that x=-3 when y=-105. Substitute these values in equation (i), to find the value of k.

$-105=\dfrac{k}{-3}$

$-105\times (-3)=k$

$315=k$

Now,

$y=\dfrac{315}{x}$

Substitute x=15 in the above equation.

$y=\dfrac{315}{15}$

$y=21$

Therefore, the value of y is 21 when x=15.

dexar [7]

Answer:

17, 10

Step-by-step explanation:

3x - 9 = 42 (opposite sides have same length)

3x = 51

x = 17

4y - 3 = 37

4y = 40

y = 10

In un rombo l'area e' di 234,95c2 , mentre l'altezza misura 12,7cm

pav-90 [236]

Answer:

la diagonale più lunga dovrebbe essere 37cm.

Step-by-step explanation:

Se cerchi la diagonale più lunga la formula dovrebbe essere questa:

A=p*(q/2)

234,95 = 12,7*(x/2)

234,95/12,7 = x/2

18,5 = x/2

18,5*2 = x

37 = x
