If the value of angle A = x + 2 and the value of angle be = 2x + 4, then the measurement of angle A will be

A30 degree

B60 degree

C105 degree

DCannot be calculated with the given data

I THINK THE ANSWER SHOULD BE 60 DEGREES THAT IS OPTION B

ANGLE A +ANGLE B=180 DEGREE
X+2+2X+4=180 DEGREE
3X+6=180
3X=180-6
3X=174
X=174/3
X=58
ANGLE A=X+2
=58+2
=60 DEGREE

A and B are supplementary angles(linear pair). So a+b=180. If we solve this equation, x+2+2x+4=180, we get A is 60.
