Question

Someone please help me with this ? Explain and give steps

Answer 1

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
