Now, notice the "tickmarks" on the angles, that means those two angles are equal, now if ∡ABC is 110, then the remaining is 70, 180 - 110, and if you subtract the 70 from 110, what's left is ∡DBC.

1/8

Step-by-step explanation:

3/4 is the same as 6/8. 6/8 plus 1/8 is 7/8. 8/8 minus 7/8 is 1/8.

How do you work out this equation

Gnom [1K]

Answer:

x is equal to negative one, and y is equal to negative four.

Step-by-step explanation:

You can do this by solving one of the equations by either x or y, then substituting it into the other. Let's solve the second one for y:

$2y = 3x - 5\\y = \frac{3x - 5}{2}$

Now we'll substitute that into the first equation:

$9x - 2y = -1\\9x - 2(\frac{3x - 5}{2}) = -1\\9x - 3x + 5 = -1\\6x + 5 = -1\\6x = -6\\x = -1$

So we now know that x is equal to -1. We can simply substitute that into one of the original equations to find y:

$2y = 3x - 5\\2y = 3(-1) - 5\\2y = -3 - 5\\2y = -8\\y = -4$

We now know that x is equal to -1, and y is equal to -4. We can also check our answer by plugging that -4 into the other equation, and see if we still get -1:

$9x - 2y = -1\\9x - 2(-4) = -1\\9x + 8 = -1\\9x = -1 - 8\\9x = -9\\x = -1$

So we know that our answer is correct.

The length of the diagonal of a square is 30square root 2 find the perimeter of the square

RoseWind [281]

Answer:

120.

Step-by-step explanation:

Using the Pythagoras theorem:

(30√2)^2 = x^2 + x^2 where x =length of each side of the square

1800 = 2x^2

x^2 = 900

x = 30.

So the perimeter = 4*30 = 120.
