No the angle of each piece should be 60 degrees, if the three pieces were to be 25 each that would only add to 75
X= -23/3, 23/3 calculate absolute value move constant to the right subtract those two numbers divide both by 3 then you get the answer i put up there

Answer:
1386 in³
Step-by-step explanation:
Volume of the composite cone = volume of a hemisphere + volume of a cone
=>Find the volume of cone
Volume of cone = ⅓πr²h
π = 3.142
r = 7 in
h = =√(15² - 7²) [using Pythagorean theorem to solve for height given the slant height and radius]
h = √(225 - 49)
h = √176 ≈ 13 in
Volume of cone = ⅓*3.142*7²*13
= ⅓*2001.454 ≈ 667 in³
=>Find volume of hemisphere.
Volume of hemisphere = ½*volume of sphere = ½*4/3πr³ = ⅔πr³
π = 3.142
r = 7 in
Volume = ⅔*3.142*7³ ≈ 719 in³
<em>Volume of composite figure = 667+719 = 1386 in³</em>
Answer:
m∠3 = 158°
Step-by-step explanation:
Angles one and two are complementary angles.
Complementary angles add up to 90°. Given the measurement of ∠1:
68° + m∠2 = 90°
68° - 68° + m∠2 = 90° - 68°
m∠2 = 22°
Angles 2 and 3 are supplementary angles.
Supplementary angles add up to 180°.
22° + m∠3 = 180°
22° + m∠3 = 180° - 22°
m∠3 = 158°
Hope this helps.
