If the length of side a is 6 centimeters, the length of side b is 4 centimeters, and the length of side C is 7 centimeters, what is the measure of ZB? Round your answer

Hi myself Shrushtee

Step-by-step explanation:

This a triangle I take it.

Side a = 6cm

Side b = 4cm

Side c = 7cm

Find angle B

Using Cosine Rule

Cos B = (a^2 + c^2 - b^2)/ 2ac

Cos B = (6^2 + 7^2 - 4^2)/ 2 x 6 x 7

Cos B = (36 + 49 - 16)/ 84

Cos B = 69/84

Cos B = 0.8214

Angle B = 34.77 degrees (2 decimal places)

Hope this helps :-).
