Answer:
P = 2x + 2y + 8
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2(l + w) ← l is length and w is width , then
P = 2(x + 5 + y - 1) ← distribute parenthesis
= 2x + 10 + 2y - 2 ← collect like terms
= 2x + 2y + 8

Answer:
∠3 is 70°
Step-by-step explanation:
∠1 is 50° since it is across from another 50° angle
and then you use the equation x+25+2x+50=180 to find x
x then equals 35°
you then use the alternate interior angle theorem to say that ∠3 is 2x, or 70°
