ANSWER :Area, the measurement of a full area and its contents in 2D!
Answer: 36
Step-by-step explanation:
Given
The ratio of Mary's to Helen's necklaces is 25:9
Mary has 100 necklaces
Suppose Helen has x necklaces
Therefore the ratio can be written like
So, Helen has 36 necklaces
Molly would need 43 feet of fencing to fence the area.
Step-by-step explanation:
We can see that the area is in the form of a right-angled triangle. Since only two sides of the triangle is given, we could utilise Pythagoras theorem to our advantage to find out the third side.
In Δ ABC
AB² (base) + AC² (perpendicular) = BC² (hypotenuse)
Substituting the values of AB as 10 feet and BC as 18 feet
AC²= BC²- AB
²
∴AC²= 224
∴AC= 14.96 cm
Amount of fence required by molly would equal perimter of the area.
⇒The perimeter of the area would equal AB+BC+AC
⇒Summing up the values of AB, AC and BC
Perimeter= 10+14.96+18= 42.96 feet which is about 43 feet
Hence, Molly would require 43 feet of fencing.
Realizing that the mental barriers of being scared to be wrong or too slow were getting in the way and stopping his kids from even attempting to solve problems, Gallin decided to change his approach.
Answer:
ASA
SSA
Step-by-step explanation:
The law of sines states that;
a/sin A = b/sin B = c/sin C
Where a,b,c are sides of the triangle and A,B,C are sides corresponding to those angles.
Hence we can use the sine rule when;
I) two angles and one side are given
2) two sides and an angle are given
Not that sine rule applies to triangles that are not right angled triangles.
