Question

ABCD is a quadrilateral in which the bisectors of angle B and angle C meet at O. If angle A = 100° and angle D = 70°, find the measure of angle BOC.​

Answer 1

Answer:

Angle BOC=95 Degrees

Step-by-step explanation:

180-50 + 35=95 Degrees

Answer 2

Step-by-step explanation:

Hello guys

Using angle sum property of quadrilateral

Angle = A + B + C + D = 360

Considered angle B and C as x

Now, Angle A = 100

Angle B =x

Angle C =x

Angle D = 70

So, Angle A+B+C+D = 360

= 100 + x + x + 70 = 360

2x = 360 - 170

2x = 190

X = 190/2

X = 95

Using amgle sum property of angle BOC

95 + angle BOC = 180

Angle BOC = 180 - 95

Angle BOC = 85

ANSWER = 85
