Question

help please! 11-15 thank you

Answer 1

Answer:

11)

45+x+x=180

2x=180-45

x=135/2

x=67.5°

12)60°

All angles in equilateral Triangle are 60°

13)

132+x+x=180

132+2x=180

x=180-132

x=48°

14)

x+2x+15=90

3x=90-15

x=75/3

x=25°

15)

x+x+10+3x-5=180°

5x-5=180

5x=180-5

x=175/5

x=35°

Step-by-step explanation:

Answer 2

Answer:

11) The angle are same so ;

by Angle sum property ;

x + x + 45 = 180

2x + 45 = 180

2x = 180 - 45

2x = 135

x = 67.5 °

angle = 67.5°

12) by Angle sum property ;

2x + 60 = 180

2x = 180 - 60

2x = 120

x = 60 °

angle = 60°

13) by Angle sum property ;

2x + 132 = 180

2x = 180 - 132

2x = 48

x = 24°

angle = 24°

14) By Angle sum property ;

90 + 2x + 15 + x = 180

3x + 15 = 90

3x = 75

x = 25 °

angle = 25°

15 ) by Angle sum property ;

x + 10 + 3x - 5 + x = 180

5x + 5 = 180

x + 1 = 36

x = 35°

angle = 35°
