Math question no guessing and show work

All angkles together are allways 180°

so 19°+55°=74°

180°-74°=106°

C has to be 106°

sina=a/11

sin55=0.819

a=11*0.819

=>a=9

sin19°=b/11

0,33=b/11

0,33*11=3,6

=> b=3,6

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
