Question

in a given figure da perpendicular to op and db perpendicular to oq and angle adb = 170° find angle aob​

Answer 1

Answer:

10°

Step-by-step explanation:

ADBO is a quadrilateral. The sum of all interior angles of a quadrilateral is 360°.

<A + <D + <B + <O = 360°

=> 90° + 170° + 90° + <O = 360°

=> 350° + <O = 360°

=> <O = 360°-350°

=> <O = 10°

Answer 2

Answer:

10 degree

Step-by-step explanation:

ADBO is a quadrilateral. The sum of all interior angles of a quadrilateral is 360 degree.

$< a+ < d+ < b+ < o \: = 360 degree$

90 degree + 170 degree + 90 degree + angle O= 360 degree

350 degree + angle O = 360 degree

angle O = 360 degree - 350 degree

angle O = 10 degree.
