Answer 1

Answer:

Answer

Step-by-step explanation:

1. We will use EXTERIOR ANGLE PROPERTY

= 110° + x = 150° = 150-110 = 40 ° Answer

2. We will again use EXTERIOR ANGLE PROPERTY

= 125° = 90° + x= 125°-90 = 35 ° Answer

3. We first use EXTERIOR ANGLE PROPERTY

= 30°+y= 60°=60°-30° = 30° Value of y

Now we will use ANGLE SUM PROPERTY

= 30°+30°+x = 180° = 180°-30+30 = 180°-60 = 140° value of x

Answers-

1. 40°

2. 35°

3, a. 30° value of y

b. 140° value of x
