Question

How to do find the angle in it??

Answer 1

Hlo friend.. Cutiepie Here.

Here is ur answer :

➡️Given

angle APB = 120

angle PBC = 15

➡️To find

angle ADB

Solution

APC is a line .

angle APB + angle CPB = 180 ( Linear pair )

120 + angle CPB = 180

angle CPB = 180 - 120 = 60

In Triangle BCP

angle BCP + angle CPB + angle CBP = 180 ( Angle sum property)

Angle BCP+ 60 + 15= 180

Angle BCP + 75 = 180

angle BCP = 180 - 75

angle BCP = 105

angle BCA = angle ADB ( Angle in same segment)

angle ADB = 105°

( angle BCA = 105° )
