Answer: 91m
Step-by-step explanation:
We set three sides of the triangle equal to 2x,6x,7x; because there is the ratio 2:6:7, which x is a common factor of these three sides.
P = a + b + c
2x + 6x + 7x = 195
15x = 195
x = 13
7x suppose be the longest side of the triangle, we plug in 13 for x, then:
7x = 7(13) = 91 m
7x+4=88
7x=84
x=12
7x-12=7*(12)-2=82
angle 1=180-82=98
I believe it is the bookshelf one
