Mr edwards = Mr r x 2
Mr r = Mr p - 3 = Mr e ÷ 2. Mr p = 30
Mr e + Mr r = 81. Mr e = 54
Mr p = Mr r + 3. Mr r = 27

Mr Edwards = 2(Mr p - 3)
Mr e = 2(mr p) - 6

Mr r = [2(Mr p) -6] ÷ 2
Mr r = [2( Mr r + 3) - 6] ÷ 2

2(Mr r) + (Mr p - 3) = 81
2(Mr p -3) + (Mr p - 3) = 81
3(Mr p - 3) = 81
3(Mr p) - 9 = 81. Hope this helps!!!
3(Mr p) + 9 = 81 + 9
3(Mr p) = 90
Mr p = 90 ÷ 3
Mr p = 30

Answer:

$\large \boxed{69^{\circ}}$

Step-by-step explanation:

Let y = m∠Y.

Then 90 - y = the complement of ∠Y

And 3(90 - y) = three times the complement of ∠Y

And 3(90 - y) + 6 = six more than three times the complement of ∠Y.

$\begin{array}{rcll}y & = & 3(90 - y) + 6 & \\& = & 270 - 3y + 6 & \text{Distribuetd the 3}\\& = & 276 - 3y & \text{Simplified}\\4y &= & 276 & \text{Added 3y to each side}\\y & = & \mathbf{69} & \text{Divided each side by 4}\\\end{array}\\m \angle Y = \large \boxed{\mathbf{69^{\circ}}}$
