Question

help...............ugh, I'm tired solving....​

Answer 1

Answer:

option d ) must be 45° or the question is incorrect

Step-by-step explanation:

see i tried in solving them as i took <BEC 1st

they hav gvn AB = BC so it shows that they are

congruent and BE is an altitude which seperates them (congruent sides) must form angle 90° with base AC by this i took <BEC = 90°

so in triangle BEC ½ <B + <E + < C = 180°

<C + <E + <C = 180° ( <B = 2 <C )

2 <C = 180° - 90° ( <E = 90° )

<C = 90°/2 = 45°

SO < B = 90° ( < B = 2 <C )

as AB = CB angle A and C are equal ( isosceles triangle)

so angle A must be 45°

this question is incomplete or options are incorrect it seems dont wory let me try again if i got the answer I'll edit this one
