until you tell me answer​

Answer 1

Answer:

the angle given figure <bac is 90 degree angle

Answer 2

Answer:

in triangle ADB

ad =bd (given)

let angle B =x

so, angle DAB =x

similarly AD=CD

angle C=x

angle DAC =x

in triangle ABC

<A+<B+<C=180

x+x+x+x=180

4x=180

x=180/4

x=45

angle A=2x=2×45=90
