∠A, ∠B, ∠C - interior angles of a triangle.
∠A 1 , ∠B 1 , ∠C 1 - exterior angles of a triangle.
∠A + ∠B + ∠C = 180°
∠A + ∠A 1 = 180°
Therefore: ∠A 1 = ∠B + ∠C ( two remote interior angles )
Answer:
An exterior angle of a triangle is equal to the sum of the two remote interior angles.
Answer:
4 cm
Step-by-step explanation:
The perimeter of the original rectangle is ...
P = 2(L+W) = 2(4x + x) = 10x
The perimeter of the larger rectangle after we add "a" to each side is ...
P = 2(L +W)
= 2((4x+a) +(x+a))
= 10x +4a = 10x +16
4a = 16 . . . . . subtract 10x from both sides
a = 4 . . . . . . . divide by 4
The length added to each side is 4 cm.

Answer: There are 5 candies of first type and 4 candies of second type.
Step-by-step explanation:
Since we have given that
Number of pieces of candy of first type = 15
Number of pieces of candy of second type = 20
We need to find the greatest number of pieces possible.
So, Greatest number of pieces = H.C.F. of 15 and 20 = 5
So, there are 5 greatest number of pieces possible.
Number of candies of first type in this piece = 
Number of candies of second type in this piece = 
Hence, there are 5 candies of first type and 4 candies of second type.
