Question

Solve for x (13x + 2) (5x - 7) (3x - 4) Thank you

Answer 1

$\huge \bf༆ Answer ༄$

As we know, sum of interior angles of a triangle is 180°

that is ~

• $\sf13x + 2 + 5x - 7 + 3x - 4 = 180$

• $\sf21x - 9 = 180$

• $\sf21x = 180 + 9$

• $\sf x = \dfrac{189}{21}$

• $\sf x = 9 \degree$

Hence, value of x is 9°

Answer 2

Answer:

• x = 9

Step-by-step explanation:

Sum of interior angles is 180:

• (13x + 2) + (5x - 7) + (3x - 4) = 180
• 21x - 9 = 180
• 21x = 189
• x = 189/21
• x = 9
