Step-by-step explanation:
7 1/6 = 86 inches
86 inches - 17 inches = 69 inches
1)6cm²
2)2
3)1000cm²
4)16x²+y²+8xy
the second and last one
....................
y=15
Because of the exterior angle theorem angle A plus angle b or equal to 146.
so you set 5y+3+4y+8=146 and solve
5y+3+4y+8=146
9y+11=146
9y=135
