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

Step-by-step explanation:
Answer:
<u>x = -14</u>
Step-by-step explanation:
<u />
<u>Divide each side by -3.</u>
- -3(x + 9)/-3 = 15/-3
- x + 9 = -5
<u>Subtract 9 from each side.</u>
- x + 9 - 9 = -5 - 9
- <u>x = -14</u>
