The rule for angles in a triangle is that they all need to add up to 180°, so you can make the three expressions equal 180 and solve:

x + 10 + x + 2 + 9x - 8 = 180
11x + 4 = 180
- 4
11x = 176
÷ 11
x = 16

So your answer is 16
I hope this helps!

Ashley should get her seeds at garden place as she gets the exact amount of seeds and spends the least amount of money.
first of all I divided 75 by the amount of seeds you get it a packet. then if that was a decimal I rounded it to the larger number (eg. 7.15 rounded to 8)
then I multiplied the cost by that number to get the amount of money itd cost.
so I got in order of the boxes(s=seeds)
75s=$18
80s=$18.4
84s=$21.84
80s=$20
so the best deal is Garden place

<h3>Answer:</h3>

PR ≈ 14.50

<h3>Step-by-step explanation:</h3>

Since ∠Q is a right angle, the area can be found from ...

... A = (1/2)bh = (1/2)(QP)(PR)

From trigonometry, we know ...

... QP = PR·cos(P) = PR·cos(36°)

... QR - PR·sin(P) = PR·sin(36°)

Substituting these values and the given area into the area formula gives ...

... 50 = (1/2)(PR·cos(36°))(PR·sin(36°))

... 100/(sin(36°)cos(36°)) = (PR)²

... PR = 10/√(sin(36°)cos(36°))

... PR ≈ 14.5015

Kipish [7]
<span>Eugene wants to buy jeans at a store that is giving $10 off everything.
Now, the tav on the jeans is marked 50% off and the original price is $49.98.
Let’s find the total cost if the 50% discount is applied before the $10 discount
Solutions:
=> 49.98 dollars * .50 = 24.99
Subtract this to get the answer:
=> 49.98 – 24.99 = 24.99 dollars, this is now that price of the jeans before 10 dollars discount is applied.</span>
