ANSWER
A) 7
EXPLANATION
The given triangles are similar
Hence the corresponding sides are in the same proportion.

Simplify the right hand side:

Cross multiply;
6(3x+4)=5×30
Expand
18x+24=180
18x=150-24
18x=126

Its an isosceles triangle
angle B = 47
and triangleADB is congruent to triangle ADC
from here we can say that BD = DC
now AD is a median and also altitude
so from here we can say angle x = 90
now in triangle ADB
90+47+y=180(ANGLE SUM PROPERTY )
y= 43
