Question

The angles of a triangle are (2x – 30°),(3x – 40°) and ( 5/2 x + 10°) Find the value of x .

Answer 1

Answer:

32

Step-by-step explanation:

Sum of angles of a triangle = 180 deg

2x - 30 + 3x - 40 + (5/2)x + 10 = 180

(15/2)x = 240

x = 480/15

x = 32

Answer 2

the answer is x=32°. process is shown above!!
