Given below are the steps of construction to construct a quadrilateral ABCD where AB = 3.5 cm, BC = 5.5 cm, CD = 2.4 cm, AD = 6.3 cm and ∠A = 45°. Which of the following steps is INCORRECT ?
Step I : Draw AB = 3.5 cm and construct ∠BAX = 45°.
Step II : With A as centre and radius AD = 6.3 cm, cut off AD = 6.3 cm along AX.
Step III : Join BD. With D as centre and radius 2.4 cm, draw an arc.
Step IV : With B as centre and radius 2.4 cm, draw an arc to cut the arc drawn in above step at C. Join BC, CD to obtain the required quadrilateral ABCD.
the correct answer should be answer D i.e. Step 4.
The given table shows the temperature of a country for 7 consecutive hours.
difference in temp is 23-(-6) that is 29 but 0 to be included then the answer is 30. Think I am correct so the answer is 30 but since 30 is not there nearest number is 29
