Question

find the value of a ​

Answer 1

Answer:

The value of a is 10

Step-by-step explanation:

Angle AOE = angle COD ( VOA)

90 = angle COD

now BOC is a line

angle BOE

Angle BOC + angle COD + angle DOE = 180

40 + 90 + 5a = 180

130 + 5a = 180

5a = 180 - 130

5a = 50

a = 50/5

a = 10

Please mark me as brainliest

Answer 2

Given

AOF = 90°

DOE = 5a

BOC = 40°

Let, AOB be x

ATP

40+x+90 = 180

=) x = 180-130 = 50

Let, COD be y

ATP

50+40+y = 180

=) y = 180-90 = 90

Let, FOE be z

ATP

50+90+z = 180

=) z = 180-140 = 40

To find DOC

ATP

90+40+50+90+40+5a = 360

=) 5a = 360-310

=) a = 50/5 = 10

Ans:- DOC = (5×10)° = 50°
