Answer 1

Answer:

When fireman directs a large amount of water at a high velocity on fire from a hose pipe, they have to hold the hose pipe strongly because of its tendency to go backwards.

Answer 2

Answer:

We know that the sum of the opposite angles of a cyclic quadrilateral is 180

o

. In the cyclic quadrilateral ABCD, angles A and C and the angle B and D form pairs of opposite angles.

∴∠A+∠C=180

o

and ∠B+∠D=180

o

⇒2x−1+2y+15=180

and y+5+4x−7=180

⇒2x+2y=166

and 4x+y=182

⇒x+y=83 ..(i)

and, 4x+y=182 ..(ii)

Subtracting equation (i) from equation (ii), we get

3x=99⇒x=33

Substituting x=33 in equation (i), we get y=50

Hence, ∠A=(2×33−1)

o

=65

o

,∠B=(y+5)

o

=(50+5)

o

=55

o

∠C=(2y+15)

o

=(2×50+15)

o

=115

o

and ∠D=(4×33−7)

o

=125
