If you look from the points at angle 73, to 42, to 131, to z, the shape makes a quadrilateral.
Since the total of the interior angles in a quadrilateral add up to 360 you make an equation:

360 = 131 + 73 + 42 + 7 + x
Re-arrange the equation to get the x alone, by subtracting:
360 - 131 - 73 - 42 = x
114 = x

So x = 114 degrees

Question 6 of 10

Maksim231197 [3]

Answer:

(2.5 , 3.5)

Step-by-step explanation:

We can use the midpoint formula . Here the points are , (2,2) and (3,5) .

• Using Midpoint Formula :-

⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }

⇒ M = ( 2+3/2 , 5+2/2 )

⇒ M = ( 5/2 , 7/2 )

⇒ M = ( 2.5 , 3.5 )

<h3>Hence the midpoint is (2.5 , 3.5)</h3>

Answer: 1/6 or 17%

Step-by-step explanation:

So on a die the only multiples of 3 are 3 and 6 so that leaves us with a 2/6 or 1/3 chance of the die and the coin is always a 50% chance so together multiplied is 1/6 or 17 %

You rent an apartment that costs $1100 per month during the first year, but the rent is set to go up 9.5% per year. What would b

uranmaximum [27]

Answer:

$2076.30

Step-by-step explanation:

In the n-th year, the rent will be ...

an = a1·r^(n-1) . . . . . . . . . r is the year on year ratio: 1+rate of increase

an = 1100·(1.095^(n-1))

Then the rent in the 8th year is ...

a8 = 1100·(1.095^(8-1)) ≈ 2076.30

The rent in the 8th year would be $2076.30.
