Question

Find x and y in the question​

Answer 1

Answer:

x=50

y=140

Step-by-step explanation:

In triangle ADC

Angle D =90

Angle C =40

Angle A = 180 - (90+40)

180 - 130 =50

Therefore x = 50 (AD divides BC)

In triangle ADB

Angle D =90

Angle A =50

Angle B = 180- (90+50)

180-140 = 40

Therefore, y =180-40 =140 (linear pair)

Answer 2

Step-by-step explanation:

To find the value of X,

In ∆ADC

angle D+ angle C+angle DAC=180

90+40+ angle DAC=180

angle DAC = 50°

angle DAC+angle BAD=90

angle DAC+angle BAD=9050 + angle BAD= 90

angle DAC+angle BAD=9050 + angle BAD= 90angle BAD(X) =40°

To find the value of Y,

In ∆BAD

angle D+angle DAB+angle B= 180

90+40+ angle B =180

angle DAB= 50°

angle B + angle y= 180.........(linear pair)

50 + angle y = 180

angle y = 130°

hope this helps.
