Triangle JKL is shown below. which of the following is not a true statement about the angles in the triangle?

Please show step by step insturctions

A, B and D are true statements.

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees. It means that

7x + 2 + 8x + 4x + 7 = 180

Collecting like terms, it becomes

7x + 8x +4x + 2 + 7 = 180

19x + 9 = 180

Subtracting 9 from both sides of the equation, it becomes

19x + 9 - 9 = 180 - 9

19x = 171

Dividing both sides of the equation by 19, it becomes

19x/19 = 171/19

x = 9

Angle J = 7 × 9 + 2 = 65 degrees

Angle K = 8x = 8 × 9 = 72 degrees

Angle L = 4x + 7 = 4 × 9 + 7 = 43 degrees

Therefore, A, B and D are true statements.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
