Help me in this answer.. anyone know this ​

Answer 1

Answer:

tell me its correct or not

Answer 2

Answer:

D=90,

Step-by-step explanation:

if AC is the angle bisector then let say

angle BAC=x then angle DAC =x

same way angle BCA=angle DCA=y let say

from the triangle

ABC

x+y+angle B=180

x+y+90=180

x+y=180-90

x+y=90

so in triangle ADC if angle x+y =90 then automatically angle D will be 90

2)

in right angle triangle hypotenuse ^2= sum of the squares of the two sides

so x^2+16= y^2+9

because AC will be common hypotenuse

y^2-x^2= 7

so that means

(y+x)(y-x) =7

if you see clearly

in order to satisfy the above conditions we have only two such numbers those are 3 and 4 so y=4 and x=3

or

we can use the congruence

ASA

so

AD =4

and

BC=3
