Question

IN A TRIANGLE ANGLE A IS EQUALS TO 2 TO B IS EQUALS TO 6 AND C IS ANGLE FIND THE MEASURE OF ANGLE A ANGLE B AND ANGLE C​

Answer 1

Answer:

angle A +angle B +angle C =180°

angle A=2B+6C

take x as common

so,x+2x+6x =180

9x=180

x=180÷9

x=20

angle A =20

angleB=2×20=40

angle C=6×20=120
