Question

15m 12m 1. PQR is a triangle, right-angled at P. IfPQ = 10 cm and PR = 24 cm, find QR. 2. ABC is a triangle, right-angled at C. IfAB= 25 cm and AC = 7 cm, find BC. 3. A 15 m long ladder reached a window 12 m high from the ground on placing it against a wall at a distance a. Find the distance of the foot of the ladder from the wall. 4. Which of the following can be the sides of a right triangle? (1) 2.5 cm,6.5 cm, 6 cm. (i) 2 cm, 2cm, 5 cm. a (iii) 1.5 cm, 2cm, 2.5 cm. In the case of right-angled triangles, identify the right angles​

Answer 1

Answer:

1) in PQR,

angleP = 90°

PQ = 10 cm, PR= 24cm,

QR^2 = 24^2 + 10^2

QR^2 = 576 + 100

QR = √676 = 26cm
