6-(1/9)+1x8
=6-(1/9)+8
=6/1-1/9+8/1 (change 6 and 8 to fractions)
=6/9-1/9+8/1
=54/9-1/9+8/1
=53/9+8/1
=53/9+8/9
=53/9+72/9
=125/9
Answer:
a
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
let x be the other leg to be found, then
155² = 124² + x²
24025 = 15376 + x² ( subtract 15376 from both sides )
8649 = x² ( take the square root of both sides )
= x
Hence x = 93 cm ← length of other leg → a
The answer is 216
