Question

find
$x + y + z$
$x = 70 digree$
$z = 40digree$
$find y$
​

Answer 1

Answer:

x = 110

y = 110

Step-by-step 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
