<span>here we can use Pythogoras' theorem.
in right angled triangles the square of the hypotenuse is equal to the sum of the squares of the other 2 sides.
hypotenuse is 19 cm. One side is 13 cm and we need to find the length of the third side.
19</span>²<span> = 13</span>²<span> + X</span>²<span>
X - length of the third side
361 = 169 + X</span>²<span>
X</span>²<span> = 361 - 169
X</span>²<span> = 192
X = 13.85 the length of third side rounded off to the nearest tenth is 13.9 cm</span>
Answer:
72 + 8x
you would multiply 8 by 9 + x
Answer:
its C
Step-by-step explanation:
Emily Dickinson's poetry was rescued for posterity by her sister (c). Emily Dickinson lived during the American Civil War, but she lived in her father's house in Amherst, Massachusetts. This area was not affected by the Civil War. She was fairly isolated as a poet and, as a result, the events of the Civil War did not play a major role in her poetry. She wrote mainly about the events in her direct environment, with no direct sense of the time in which she lived. Her world consisted of her own home and the surrounding countryside.
