Using a standard normal table, you can look up the number of standard deviations for the 98% value which will be 2.054. Then multiply this number by the standard deviations and add that to the mean to get the desired value. So
2.054 * 15 + 100 = 130.81
Rounding to the nearest whole number gives you 131.</span>
So, you already know that angle CBD is 68 degrees, and the complementary angle to angle CBD is angle CBA. These angles together make 180 degrees because segment DBA is a straight line consisting of angles CBD and CBA. 180-68(the angle you already know) is 112 degrees for angle CBA. Then you repeat this process to find the other angles
The answer is true;
because if a triangle had more than one obtuse angle it would become like a rhombus or something else so it is not possible to remain a triangle and have more than one obtuse angle c:
The volume of the <span>cylinder </span>= π r² h
r ⇒⇒⇒ radius
h ⇒⇒⇒ height
r = 5 ft and h = 3 ft
volume = π * 5² * 3 = 235.62 ft³
rounding to the nearest ft² = 236 ft³
The fourth choice is the correct answer
