Question

angles of a triangle are(3x)°,(2x-7)°anf (4x-11)°.find the measure of x and each angle of the triangle​

Answer 1

Step-by-step explanation:

3x+2x-7+4x-11=180 ...............(angle sum property)

9x-18=180

9x=180+18=198

x=198/9

x=22

Angle 1=3*22=66

Angle 2=2*22-7

=44-7=37

Angle 3=4*22-11

=88-11=77
