Answer:
BE = 49
Step-by-step explanation:
In triangle BDC
65^2=56^2+BD^2
65^2-56^2=BD^2
4225-3136=BD^2
1089=BD^2
33=BD
In triangle FDE
65^2=63^2+DE^2
4225-3969=DE^2
256 = DE^2
16=DE
since ED+DB=BE
THEREFORE
16+33=BE
49=BE
No. Two angles will have to be the same and the third angle will just be 180° minus twice the smaller angles.
So if we let the equal angles equal a, and the large angle equal be we have:
2a+b=180
So there are infinitely many values that a and b can have.
a=(180-b)/2, so the smaller equal angles have the range (0,90)
b=180-2a, so the larger has a range of (0,180)
