Construct a suitable right angled triangle on the number line. Note that √5 = √(2^2 + 1...height = 1] √7 = √((√3)^2 + 2^2) ..............[Draw a right angled triangle with base = √3, height = 2] Hope...
補充多少少LA 如果係 centroid and incentre 係咩情況都lie inside 三角形 for circumcentre: 銳角(acute): inside 直角( right ): lie on 鈄邊(hypotenuse) 鈍角(obtuse): outside for corthocentre: 銳角(acute): inside 直角( right ): lie on 直角既頂點vertex of right angle 鈍角(obtuse): outside
...rest of the 8 books. P(1stvolume on the left hand and the 10th volume on the right end) = 1 / 10P2 = 0.01111 c. Consider the cases: ...

Let R and H be the base radius and height of the circular cone respectively, then its volume is πR2H/3. Then let r and h be the base radius and height of the cylinder respectively. We have, by similar triangle: (H - h)/H = r/R 1 - h/H = r...
Calculated length L = 20cm/sin30 = 40cm Possible error of angle is +/- 1 degree Max of L will be 20cm/sin29 = 41.25cm = 40cm + 1.25cm Min of L will be 20cm/sin31 = 38.83cm = 40cm - 1.17cm The error is +1.25 -1.17 When the error in angle...
x=-2 y=-3 It is because the number line is -4, -3, -2, -1. -1,-4 兩個之間得-2, -3 同埋-2是在-3右邊
