Question

Q9. If the angles of a triangle are ( 4x - 13). (3x - 1) and ( x + 2), then
find the value of x.

Answer 1

Answer:

21

Step-by-step explanation:

(4x-13)+(3x-1)+(x+2)=180

8x-12=180

8x=180-12

8x=168

x=21

Answer 2

Answer:

24 degrees

Step-by-step explanation:

sum of all angles of a triangle = 180

(4x-13) + (3x-1) + (x+2) = 180

8x - 12 = 180

4(2x-3) = 180

2x - 3 = 180/4 = 45

2x = 45 + 3 = 48

x = 48/2 = 24 degrees
