What is the length of AB⎯⎯⎯⎯⎯? Enter your answer as a decimal in the box. Round only your final answer to the nearest tenth. cm A horizontally-aligned scalene triangle A B C. Side A C is labeled as 18 centimeters. Side B C is labeled as 12 centimeters. Angle C is labeled as 79 degrees.

AB = 19.6 cm

Step-by-step explanation:

Let AB be represented by c. Applying the cosine rule, we have;

= + - 2ab Cos C

  = + - 2(12 x 18) Cos

  = 144 + 324 -432(0.19081)

  = 468 - 82.4299

= 385.5701

c =

c = 19.6359

The side AB of the given triangle is 19.6 centimetres.

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math
