Question

Find the Lettered angles in the figure​

Answer 1

Step-by-step explanation:

In ABD

<ABD = 60

<ADB = 180 - 90 = 90

so angle sum property of triangle is 180

<BAD = 180 - (60+90)

= 180 - 150

= 30

In ACD

<ADC = 90

<CDA = 40

so angel sum property of triangle is 180

<ACD = 180 - (90+40)

= 180 - 130

= 50

Answer 2

Answer:

x = 30 and y= 50

Step-by-step explanation:

In ∆ADB,

x + 60 + 90=180

x = 180 - 150

x = 30

Similarly,In ∆ADC,

y + 40 + 90= 180

y = 180 - 130

y = 50
