Answer 1

Answer:

find ang b from ang a and c then find x from ang b and. d using ext ang property .

sum of 2 int oppo ang = ext ang

Answer 2

Answer:

x = 109°

Step-by-step explanation:

In triangle ABC, 34° + 30° + x = 180°

So, x = 180° - 64

= 116°

We know the property, that the angle of an exterior angle is equal to the sum of the opposite two interior angles.

So, in triangle BDE, (let the angle <BED = y )

116° = y + 45°

y = 71°

The line segment BC is 180°.

So, y + x = 180°

71 + x = 180°

x = 109°
