Find the missing side or angle. round to nearest tenth
A=18
B=28
C=100
a=?

The missing side, a = 100.50

Step-by-step explanation:

The given information are;

A = 18

B = 28

C = 100

a = Required,

The number of data points in the definition = 3, therefore, the figure is a three sided figure or a triangle

The sum of the given data is 18 + 28 + 100 = 146 which is less than the sum of the interior angles of a polygon, the minimum of which is 180° for a triangle.

However, the length of the two sides A and B are less than the third side C, therefore, the sides need more length for them to form a triangle

The fourth required information can be taken as the fourth side of a trapezium, to give;

Length of a = √((28 - 18)² + 100²) = 100.499, which can be written to the nearest 10th as 100.50.
