Find the value of AB.
13
12
A
В
AB = [?

Step-by-step explanation:

CD is perpendicular to AB

If any radius or diameter is perpendicular to any chord of a circle, then it bisects that chord.

Mean, AB= BE = 12

So, AB = 2(BE)

2(12)= 24

so your answer will be 24

hope it helps..

have a great day!!

Step-by-step explanation:

or, 2x° + (3x +5)° = 90° [ Complementary angles]

or, 5x° + 5 = 90°

or, 5x° = 90°- 5

or, x = 85/5

: x=17°
