Inscribed angles
Please help

a = 72° b = 88°

Step-by-step explanation:

We know in the cyclic quadrilateral opposite angles are supplementary so

a + 108° = 180° { being opposite angles of cyclic quadrilateral }

a = 180° - 108°

a = 72°

b + 92° = 180° { being opposite angles of cyclic quadrilateral }

b = 180° - 92°

b = 88°

he spend 5.1 minutes chatting with his friends.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
