Step-by-step explanation:
mXYZ+mXYW=180°(being straight angle)
mXYW =180-115
mXYW=65
now,
mXWY+mWXY+mXYW=180°(sum of angle of triangle)
mXWY=180-110
mXWY=70°
hope it helps.
Answer:
<u>h = V/r²</u>
Step-by-step explanation:
The formula is :
- V = r²h (actually 1/3πr²h in real life)
Solving :
- Dividing both sides by r²
- V/r² = r²h/r²
- <u>h = V/r²</u>
A
If she always sells 110 then it can be less but we dont know if its equal or if she sold more
Since they are vertical angles, they equal each other. Therefor the equation would be: 30x-29 = 20x+21
10x = 50
X = 5
After, you plug whatever x is back into the other equations.
20(5)+21 = 121 and 30(5)-29 = 121
