In the give kite PQRRS, angle PQR= 70degrees and angle PSR = 80 degree, find (i)angle SRO (ii)angle OPQ (iii)angle SPQ (iv)angle PSQ
Answers
a. When an object falls freely to the ground, it is under the effect of a constant force known as force of gravity. No other forces act on it. Hence, from Newton's second law of motion, we can say that this constant force of gravity accelerates the the freely opposite, their effects do not get cancelled because these action and reaction forces do not act on the body. ball has s ball than a cricket ball moving with the same velocity.
b. Even though the magnitudes of action force and reaction force are equal and their directions are opposite, their effects do not get
cancelled.
c. It is easier to stop a tennis ball as compared to a cricket ball, when
both are travelling with the same velocity.
d. The velocity of an object at rest is considered to be uniform...
Answer:
exterior angle =70
hence complementary interior angle =180–70 =110
one of the three angles of triangle is 110degree
hence sum of 2 remaining angle =180 -110 =70
we have to distribute 70 degrees in 3:4 ratio
3+4 =7
for 7 =70 degrees so far 3 =70*3 /7 =30degrees
similarly other angle is =70*4/7 =40degrees or 70–30=40degrees
Answer :The angles of triangle are 30 degrees,40degrees &110 degrees
