Question

calculate the value of x​

Answer 1

Answer:

2: 25 degree

3: 60 degree

Step-by-step explanation:

2: 3x-5+x+20 +65 = 180

== 4x =100

== x = 25

3: 2x + 2x + x +60 = 360

== 5x=300

== x =60

Answer 2

1. Angle sum property:

3x-5+x+20+65=180°

4x-5+45 =180°

4x-5 =180°-45

4x-5 =135°

4x =135°+5

4x =140°

x =140°/4

x = 36°

2. x+2x =180° (Linear Pair)

3x =180°

x =180°/3

x =60°

60°+2x =180° [Linear Pair]

2x =180°-60°

2x =120°

x =120°/2

x =60°
