Question

look at the following figure and find the value of x and y. Name the type
of triangle (Justify your answer)(Write proper solution of the question)
​

Answer 1

Answer:

can you tell what is the angle ACD

it is not visible

Step-by-step explanation:

$here \: we \: know \: that \: sum \: of \: two \: angles \: is \: 180$

$therefore \\ angle \: \: acd + angle \: acb = 180$

$= angle \: acd \: + x = 180$

substitute value of angle ACD you will find the value of x

$then \: in \: triangle \: abc \: \\ angle \: a + angle \: b \: + angle \: acb = 180$

$therefore \: \\ 40 + x + y = 180$

from this you will find the value of y
