Question

If three angles of a quadrilateral are each equal to 75degrees then find the fourth angle

Answer 1

Su

$sum \: of \: the \: all \: interior \: angle \: of \: a \: quadrilteral \: \: is \: 360$

Let the other angels be x

Then,

75+75+75+x = 360

225+x = 360

X= 360-225

X= 135

$fourth \: angle = 135 {}^{0}$

Hope it will be true
