Help please i need so much help

6) in order  51º; 18º;123º;39º

7) in order   51º; 34º;95º;38º;47º;74º;59

Step-by-step explanation:

a triangle is 180º so 180-72-57=51

x+72=90        x=18

a line is 180º  so 180-57=x         x=123

a triangle is 180º  so 180-123-18=39

diagonals are congruent

180-129=51

180=51-95+x         x=34

180=47+95+x        x=38

180=59+x+47        x=74

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
