Solve each triangle. Round your answers to the nearest tenth.
​

The value of is , the length of BC and AC is 28 units and 25 units respectively.

Step-by-step explanation:

To calculate the value of each part of the triangle, we use:

1) Angle sum property

2) Law of sines

Starting with 1:

Calculating by angle sum property:

Applying 2:

The Law of sines relates the length of the side with the sines of the angle opposite to it.

Similarly,

Hence, the value of is , the length of BC and AC is 28 units and 25 units respectively.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
