60 / 2 = 30
30 * 5 = 150
he had $150 at first
60, the amount he was left with was 2/5 or 40% of his original amount
8/20as well，since the number of green beads and yellow beads is the same，so equal probability
Answer:
6√3 = x y =12
Step-by-step explanation:
Since the two sides of the triangles have equal angles then two sides have equal length
the sum of interior angles of triangles is 180° then the last angle is 60°
then the triangles have perfect sides of 12
y = 12
to calculate x
sin Ф = opposite/hypothenus
sin 60° = x/12
sin 60° = √3/2
( √3/2 ) x 12 = x
6√3 = x
X= 3x + 6 / 3 = 6 (im pretty sure)
Answer:
71
Step-by-step explanation:
78+31=109 so 180-109=71
