In the diagram of circle o, chords ac and bd are perpendicular to each other.
a.95°
b.90°
c.85°
d.80°

step-by-step explanation:

alright, lets get strarted.

the chords ac and bd are given as perpendicular.

it means, angle dec is given as 90 degrees.

to find angle aed, we need to subtract this angle from 180.

so, angle aed =

it means ae and de are making 90 degree angles with each other.

means the option b is correct :   answer b

hope it will : )

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
