The answer is 160. There are 160 boys in the school. Take 360 divide by 9, then multiply by four.
Answer:
66°
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
x + y = z
5n − 19 + n + 7 = 144 − 6n
6n − 12 = 144 − 6n
12n = 156
n = 13
m∠z = (144−6n)°
m∠z = (144−6×13)°
m∠z = 66°
(x+4), (y-1) because the figure is translated 4 units to the right and 1 down.
Express 0.31 as a fraction and express 0.2 as a fraction
