Question

In triangle ABC,angle A=90°,AD perpendicular BC and angle B=45°.If AB=X,find AD in terms of X​

Answer 1

Step-by-step explanation:

In ∆ABD,

angle D=90°

B=45°

A=180-(90+45)

=45°

the angles are in the ratio,

45:45:90

= 1:1:√2

=AD:BD:AB

= AD:X

AD÷X= 1÷√2

√2AD=1

AD=1÷√2

Answer 2

Answer:

$152 log(3 = \cot(?) )$
