Answer:
60 milligrams
Step-by-step explanation:
just cross multiply! percentages are just fractions of 100. so you can say that 
multiple 75 by x and 45 by 100 and you get
4500=75x
divide both sides by 75 and you get 60
Angle Side Angle Theorem (ASA)
The Angle Side Angle Postulate (ASA) says triangles are congruent if any two angles and their included side are equal in the triangles. An included side is the side between two angles.
Answer:
x = 16°
H = 46°
I = 55°
J = 39°
Step-by-step explanation:
Since the whole figure is 180°
Deduct 180 by the numbers mentioned above in order to find x.
180 - 2 - 9 - 9 = 160
3x + 4x + 3x = 10x
10 x = 160
x = 160 ÷ 10 = 16
Since we know what x is, we can find all the angles in the figure.
Angle at H = 3 x 16 - 2 = 46°
Angle at I = 4 x 16 - 9 = 55°
Angle at J = 3 x 16 - 9 = 39°
An equivalent ratio of 64:60 is 16:15.
