Question

19. Find the value of x in the given figure:

2x +
x
+ 3
3x-4)
3x - 4
C
a) x = 32.3
b) x = 29
c) x = 27.7
d) x = 31

Answer 1

Answer is B.... 29

The summation of the interior angles of a triangle =180

Therefore... 2x+7+x+3+3x-4=180

Grouping like terms give.... 6x+10-4 =180

6x+6. =180

6x =180-6

6x. =174

Dividing both sides by 6

Hence x=29
