What is the value of y?
оа. 73°
ов. 549
ос. 63°
op. 1269

C

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

y + y + 54 = 180

2y + 54 = 180 ( subtract 54 from both sides )

2y = 126 ( divide both sides by 2 )

y = 63° → C

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
