What is the value of p?
(Geometry Question)

p = 92

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angle

p+45 = (p-47)+p

Combine like terms

p+45 = 2p-47

Subtract p from each side

p-p+45 = 2p-p-47

45 = p-47

Add 47 to each side

45+47 = p-47+47

92 = p

8 - 2 + 5 x ( 16 + 66 ÷ 2)

Do the ÷ in the bracket:

= 8 - 2 + 5 x ( 16 + 33)

Do the operation in the bracket:

= 8 - 2 + 5 x 49

Do multiplication:

= 8 - 2 + 245

Do subtraction:

= 6 + 245

Do addition:

= 251
