Answer:
(12,10)
Step-by-step explanation:
Answer:
The formula to find the perimeter of a rectangle is 2L + 2W.
Here L=5 and W=2; hence:
2*5+2*2
=14
The perimeter is 14.
The formula to find the area of a rectangle is length × width; hence:
5*2=10
The area of the rectangle is 10.
22 + (-18) =4 , I think this is right

Answer:
Step-by-step explanation:
Two 30 - yes, 180 - 30 - 30 = 120. It is possible for 2 angles to be 30, the remaining angle would also be 120
Two 60 - yes, 180 - 60 - 60 = 60. It is possible for 2 angles to be 60, the remaining angle would also be 60
Two 90 - Not possible. The entire angles of a triangle have to equal 180, this would mean only 2 angles.
