If you find the total amount of birds, which is 27... Then you read "Number of Geese to total birds"
15 to 27 or
15/27 or
15:27
Answer:
x = 20
y = 10
m∡8 = 110°
Step-by-step explanation:
m∡1 + m∡2 = 180
5x + y + 3x + y = 180
8x + 2y = 180
m∡1 = m∡8 (they are alternate-exterior angles and are congruent)
5x + y = 3x + 5y
2x = 4y
x = 2y
Substitute '2y' for 'x' in 8x + 2y = 180
8(2y) + 2y = 180
18y = 180
y = 10
x = 2(10)
x = 20
m∡8 = 3(20) + 5(10) = 110°
It helps by grouping them up into equal groups by counting how many groups there are

Answe r: a=bc+8bd/d
Hoped I helped!
Its 1 and 2 because 5 and 4 look similar but its not as close as 1 and 2 based on the photo u put
