Question

In the given figure, if ZA = 90°, ZB = 90°, OB = 4.5 cm, OA = 6 cm and AP = 4 cm, then QB
B​

Answer 1

Answer:

QB=3cm

Step-by-step explanation:

in triangleAOP and triangle QOB

angel A= angle B= 90°

angel AOP = angle QOB (vertically opposite angles)

OA≠OB

triangle AOP and triangle QOB are similar angle's

OA/OB=AB/QB (in similar triangles the ratio of corresponding sides are constants)

QB=AB×OB/OA

QB=3cm
