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
Answer:
y^2-5y-4
Step-by-step explanation:
Let y^2-5y+1 =A
Required polynomial=B
A-B=5
B=A-5
B=y^2-5y+1 -5
B=y^2-5y-4
Hence,Required polynomial=y^2-5y-4
3 √2 3√2(2√3 + 5√2) 30 + 6√6 30 + 6√6
------------- = ----------------------------- = ------------------ = ----------------
2√3 - 5√2 (2√3 - 5√2)(2√3 + 5√2) 12 - 50 -38
-15 - 3√6
= ---------------- answer
19
