Answer:
Step-by-step explanation:
( 2x - 8 )° = ( x + 28 )° ⇒ x = 36
<em>m∠1</em> = <em>m∠4</em> = 180° - ( 36 + 28 )° = <em>116 </em>°
<em>m∠2</em> = 123° - 64° = <em>59</em> °
<em>m∠3</em> = <em>123 </em>°
77.20 i think i did it in my head and with a caluclator
Answer:
-2/8
Step-by-step explanation:
-3r-9+7=5r
-2=5r+3r
r=-2/8
hope this helped you( ꈍᴗꈍ)
Answer:
below
Step-by-step explanation:
add -36 to both sides
divide both sides by 2
This is a quadratic equation
let's solve it by graphing it
The solution are the x-coordinates of the intersection points
The x-coordinates of the intersection points are approximatively -1.6 and 5.6

Volume of cone:
-------------------------------------------------
Volume = 1/3 πr²h
-------------------------------------------------
Find Height:
-------------------------------------------------
Given that the radius = 5 and the volume = 100, we will substitute these values into their respective variable and solve for height.
Volume = 1/3 πr²h
100 = 1/3 π (5)²h
h = 100 ÷ 1/3π(25)
h= 4 units (Nearest whole number)
-------------------------------------------------
Answer: The height is 4 units.
