<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:
Step-by-step explanation:
Answer:
161 ft squared
Step-by-step explanation:
8 x 5 x 2 = 80
8 x 7 = 56
5 x 5 = 25
80 + 56 + 25
56 + 25 =81
80 + 81 = 161
161 ft squared
