Answer:
0.318
Step-by-step explanation:
The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that a = 8.6 in, b = 13.9 in. and c = 16.5 in. Using cosine rule:
c² = a² + b² - 2abcosC
16.5² = 8.6² + 13.9² - 2(8.6)(13.9) * cosC
C = 91.2°
Also:
a² = b² + c² - 2bccosA
8.6² = 16.5² + 13.9² - 2(16.5)(13.9) * cosA
A = 31.4°
A + B + C = 180° (angles in a triangle)
31.4 + B + 91.2 = 180
B = 57.4°
The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°

The difference between 98 and 78 times 11
the quantity 98 minus 78 times 11
Depending on what bird you would use centimeters and inches
First arrange them in ascending order:-
17 20 24 25 30 32 35 38 40 42
The median = mean of middle 2 numbers = (30+32)/2 = 31
Lower quartile = 24 and upper quartile = 38
Inter quartile range = 38 - 24 = 14
Its the first choice.
