Find the height of an equilateral triangle whose side measures 56 cm

pychu [463]

Answer:

48.5 cm

Step-by-step explanation:

For this you can use the Pythagorean theorem. You know that your hypotenuse will be 56 cm, and one side will be half of that, 28. This sets up the equation:

a^2+28^2=56^2

So, a^2 is 2,352

And a, rounded to the nearest hundredth, is 48.5 cm

Hope this helps :)

$\sf\huge \green{\underbrace{\red{Answer}}}:$

y = 4

Correct option is (C)

Step-by-step explanation:

-2x - 5y = -2 {taking minus(-) common}

⠀

2x + 5y = 2 [equation 1]

⠀

3x + 6y = -3 {taking 3 common}

⠀

x + 2y = -1 [equation 2]

⠀

{taking 2y of equation 2 on RHS}

⠀

x = -1 - 2y [equation 3]

⠀

{substituting of equation 3 in equation 1}

⠀

2(-1 - 2y) + 5y = 2

- 2 - 4y + 5y = 2

y - 2 = 2

y = 2 + 2

⠀

y = 4
