**Answer:**

(a) 42.3°

**Step-by-step explanation:**

Side 'a' is the shortest of three unequal sides, so angle A will be the smallest angle in the triangle. Its measure can be found from the Law of Cosines.

a² = b² +c² -2bc·cos(A)

cos(A) = (b² +c² -a²)/(2bc) = (21² +25² -17²)/(2·21·25) = 777/1050

A = arccos(777/1050) ≈ **42.3°**

**The measure of angle A is about 42.3°**.

<u><em>Additional comment</em></u>

The smallest angle in a triangle can never be greater than 60°. This lets you eliminate choices that exceed that value.

Answer;

The equation of the line is

3y = 4x + 4

Explanation;

Mathematically we can write the equation of a straight line in the form

y = mx + c

where m is the slope

Since the old line would parallel to the new line, then they have the same slope

This means that the slope of the new line will be 4/3

Now, we had yet slope and a point, we need to write the equation of the line

mathematically;

y- y1 = m(x - x1)

In this case m = 4/3, (x1,y1) = (5,-8)

Thus;

y+ 8 = 4/3(x-5)

y+ 8 = 4/3x -20/3

y = 4/3x -20/3 + 8

Multiply through by 3

3y = 4x -20 + 24

3y = 4x + 4

3+7=10

55/10=5.5

5.5 x 3=16.5

5.5 x 7=38.5

16.5 : 38.5
