sin (x) = -1

arcsin (-1) = x

x = -90

and multiples of 360

x =-90, 270,....

x =-90 + 360n where n is an integer

or in radians

-pi/2 + 2*pi *n where n is an integer

The lengths of the sides of a triangle are in the extended ratio 44 ​: 55 ​: 77. the perimeter of the triangle is 6464 cm. what
joja [24]
44x + 55x + 77x = 6,464 centimeters.
x = <span> <span> <span> 36.7272727273 </span>

Therefore the sides are
44*</span></span><span><span>36.7272727273 = 1,616 </span>
55*</span><span>36.7272727273  </span>= 2,020
77* <span> <span> <span> 36.7272727273 </span> </span> </span> = 2,828

OR maybe that's another of those infamous Brainly typos.

4x + 5x + 7x = 64 centimeters.
x = 8

Therefore the sides are
4*8 = 32
5*8 = 40 and
7*8 = 56 centimeters

Hitman42 [59]

Answer:

a = - 27

Step-by-step explanation:

- \frac{2}{3} a - 6 = 12 ( add 6 to both sides )

- \frac{2}{3} a = 18 ( multiply both sides by 3 to clear the fraction )

- 2a = 54 ( divide both sides by - 2 )

a = - 27
