Answer 1

Step-by-step explanation:

We know that, sum of supplementary angle is equal to 180o. And also, opposite angles ∠P and ∠R are equal in parallelogram. Therefore, the other three angles of parallelograms are 60o, 120o and 120o

i hope it will help u

Step-by-step explanation:

7/5×(−3/12)}+{7/5+5/12}

Taking common factor, we get

=7/5×(−3/12+5/12)

=7/5×{(−3+5)/12}

=7/5×2/12

We get,

=7/30.
