Diagram shows an irregular hexagon PQRSTU.Fine the value of X + Y=
Lynna [10]
To find the value of x+y, we will first find the sum of all the interior angles of the hexagon.The sum of the interior angles in a hexagon is always equal to 720 degrees.

All the angles in the diagram are in terms of x or y except for angle t. However, we know that the corresponding exterior angle is 30 degrees. The sum of angle t and 30 is 360. We can solve this in an algebraic equation.

t+30=360
Subtract 30 from both sides
t = 330

Now, we can solve for the values of x+y. We can set this up in another algebraic equation.

x+x+x+2y+y+30=720

Combine like terms:
3x+3y+30 = 720

Subtract 30 from both sides:
3x+3y = 690

Divide both sides by 3:
\frac{3x + 3y}{3} =  \frac{690}{3}
x+y = 230

The sum of x and y is 230.

WARRIOR [948]

Answer:

- \frac{7}{4}

Step-by-step explanation:

Given

- \frac{7}{10} ÷ \frac{2}{5}

Leave the first fraction

Change division to multiplication

Turn the second fraction upside down

= - \frac{7}{10} × \frac{5}{2} ← cancel 5 and 10 by 5

= - \frac{7}{2} × \frac{1}{2}

= - \frac{7(1)}{2(2)}

= - \frac{7}{4}
