Answer:
A. The length of the third side is approximately 5 feet.
B. A =
, B =
and C =
.
Step-by-step explanation:
Let the triangle be ABC. Given two sides and an included angle, let us apply the cosine rule to determine the third length.
A. Let side a = 6 feet and c = 3 feet, thus;
=
+
- 2ac Cos B
=
+
- 2(6 x 3) Cos 
= 36 + 9 - 36 x 0.5
= 45 - 18
= 27
b = 
= 5.1962
b = 5.2 feet
b ≅ 5 feet
The length of the third side is approximately 5 feet.
B. Given that B =
, then let us apply the Sine rule to determined the measure of A.
=
So that,
= 
Sin A = 
Sin A = 0.99923
A =
0.99923
= 87.75
A ≅ 
Since the sum of angle in a triangle =
.
Then,
A + B + C = 
+
+ C = 
+ C = 
C =
- 
= 
C = 
Thus,
A =
, B =
and C =
.

For this problem, you can start by taking the 35 and dividing it by 5 to get 7. Then you need to take 300 and divide that by 5 to get the right proportions. Then you can take your new number from 300 and divide that by 7, and you should not be on the right path because I'm probably an idiot.
Sorry bout it

Answer:
At the positive integer value of x=7 the quadratic function begin to exceed the linear function
Step-by-step explanation:
we have
using a graphing tool
see the attached figure
For x < -1.405 and x > 6.405 the quadratic function begin to exceed the linear function
so
At the positive integer value of x=7 the quadratic function begin to exceed the linear function
