Answer:
dab= 43 degrees
Step-by-step explanation:
this is because of a property in geometry (I dont remember the name) that says when your lines are parallel to each other with that line through the center like that, the degrees cross
Simple,
writing an equation to find the sides,
x+2+x+2+x+x=44
4x+4=44
Subtract 4 from both sides, making the equation look like this,
4x=40
Divide by 4
x=10.
To check it, just plug it back into original equation.
10+2+10+2+10+10=44
It works. :)
Step-by-step explanation:
24 ÷ 3:4
= 24 / 3 / 4
Basics
a / b / c = a / b / c / 1
....1 is normally invisible since a number
divided by 1 is itself. i wrote 1 down to show the reciprocal property.
a/b/c/1 = a/b × 1/c = a/bc ...Flip the number you're dividing with.
24/3/4 = 1/24 × 3/4 = 3 / 96 = 3 × 1 / 3 × 32 ...cancel the 3s'
= 1 / 32.
Answer:
QR=17
Step-by-step explanation:
![x=7\\\\QR=12+x-2\\=12+(7)-2\\QR=17](https://tex.z-dn.net/?f=x%3D7%5C%5C%5C%5CQR%3D12%2Bx-2%5C%5C%3D12%2B%287%29-2%5C%5CQR%3D17)
1. 4n - 6n - 6 > 12
-2n > 18
n < -9.
2. 5 > 5(12-a)
5 > 60 - 5a
5a > 55
a > 11
3. 2s + 20 < 119 - 9s
11s < 99
x < 11
