The law of cosines can be used to find the angle. The sides adjacent to that angle are a=34, b=38, and the side opposite is c=8. Then the angle is found from ...

c² = a² +b² -2ab·cos(C)

cos(C) = (a² +b² -c²)/(2ab)

C = arccos((a² +b² -c²)/(2ab))

C = arccos((34² +38² -8²)/(2·34·38)) = arccos(317/323)

C ≈ 11.06°

From the footballer's viewpoint, the goal posts are 11.06° apart.

Answer:

With given side lengths a triangle <u>could not</u> be created.

Step-by-step explanation:

Given:

First side length = 7.7 cm

Second side length = 4.0 cm

Third side length = 1.7 cm

We need find whether this could be the side length of the triangle.

Solution:

Now we know that;

By Triangle In equality property which states that;

"Sum of the two side length of the triangle must be greater than third side."

It should fulfill all three conditions;

So we will find the same.

Condition 1:

First Side + Second Side > Third side

$7.7+4.0>1.7\\\\11.7>1.7$

Hence This condition is true.

Condition 2:

Second side + Third Side > First side

$4.0+1.7>7.7\\\\5.7>7.7$

Hence This condition is False.

Condition 3:

First side + Third Side > Second side

$7.7+1.7>4.0\\\\9.4>4.0$

Hence This condition is true.

Since One of the condition is false hence With given side lengths a triangle could not be created.
