Answer: 5\sqrt{3\\}

Step-by-step explanation:

This triangle is a 30-60-90 triangle. This means that: x = 2a where a is the shorter leg of the triangle and x is the hypotenuse, and b = a\sqrt{3\\} where b is the longer leg of the triangle.

Hypotenuse = 2 * the length of the shorter leg

Longer leg = \sqrt{3\\} * the length of the shorter leg.

Since just visually speaking, y is the longer leg and 5 is the shorter leg, let's substitute y and 5 into the equation solving for the length of the longer side:

y = \sqrt{3\\} * 5

y = 5\sqrt{3\\}

2)<br> 8xy -- 3y + 2 ( 9x - 5y + 4 ) if x = 3, y = - 4
Scilla [17]

Answer:

8xy-3y + 2(9x-5y+4) = 18

Step-by-step explanation:

We need to find the value of the given expression:

8xy-3y + 2(9x-5y+4) ....(1)

when x = 3 and y = -4

Put the values of a and y in equation (1)

8×3×(-4)-3(-4)+ 2(9×3-5(-4)+4)

= -96 +12 + 2(27 + 20 +4)

= -84 + 2(51)

= -84 + 102

= 18

Hence, the value of the given expression is 18.
