Question

Step by step explanation pls. In my textbook answer key answer is x= 140 and y = 110​

Answer 1

Step-by-step explanation:

Here B= 70 According to This Triangle C is same quardinent

or According to Triangle Rule y is as same its equivalent 70 is

So Sum of Corner of Triangle is 180°

AB = 40 °

BC = 70 °

AC = ?

$70 + 40 = x \\ \\ 70 + 40 = 110 \\ \\ 180 - 110 = 70$

According To Triangle Rule Sum of Triangle Corner is 180

if Inner Side Come 70 Its Outer Side Also Will Be 70

Than the Value of x is upper Side 70 + down side 70

70+70=140

y is 70+40=110

hence y = 110
