Question

Find


`x + y + z`

`x = 70 digree`

`z = 40digree`

`find y`
​

Answer 1

x = 110

y = 110

Explanation:

Here, we are going to apply an important triangle property

The sum of opposite interior angles equal the exterior angle of the third side

Thus, we have that;

y = 70 + 40 = 110

As we can see, the third angle in the triangle will be;

180-70-40 = 110

This is because sum of angles = 180

Thus, applying the exterior angle relationship,

x = 70 + 40 = 110
