Answer 1

ANSWER :

The ∆ABD is an isosceles triangle

Because

AD = BD

We know that

Isosceles triangle : The triangle with two equal sides and sides opposite angles are also equal.

So, now

angle BAD = angle DBA

angle BAD = 29°

Using angle sum property

angle BAD + angle DBA + angle ADB = 180°

29° + 29° + angle ADB = 180°

angle ADB = 180° - 58°

angle ADB = 122°

We know that

Exterior angle = sum of interior opposite angles

Here , exterior angle = angle ADC

angle ADC = angle DAB + angle DBA

angle ADC = 29° + 29°

angle ADC = 58°

Taking ∆ADC

It is an isosceles triangle

Because,

AD = DC

angle CAD = angle DCA

TO FIND :

angle x

angle x = angle DCA

Using angle sum property

angle CAD + angle DCA + angle ADC = 180°

x° + x° + 58° = 180°

2x° = 180° - 58°

2x° = 122°

x° = 61°

Hence x = 61°

Answer 2

Answer:

According to universal law of gravitation and Newton third law, we know that the force of attraction between two objects is same but in opposite direction. Thus the earth attracts the moon with the same force as the moon exerts on earth but in opposite directions.
