Question

Find the angle measure X in the following ​

Answer 1

Answer:

83° + 110° + 90° + y = 360°

=> 283° + y = 360°

=> y = 77°

Therefore ,

x = 180 - 77

= 103°

Step-by-step explanation:

Answer 2

Given ,

The angles of quadrilateral are 60 , 130 , 120 and x

As we know that ,

The sum of all angles of quadrilateral is 360

Thus ,

$\sf \mapsto 60 + 130 + 120 + x = 360$

$\sf \mapsto 310 + x = 360$

$\sf \mapsto x = 50$

★ The angle is 50

Remmember :

• The sum of all angles of triangle is 180
