Question

Hey there!
Please help me in this question.
Please give the correct answer and i will mark you as the brainliest :)

Answer 1

Step-by-step explanation:

x+3)+(x+20)+(x+7) =180 ( angles on st.line )

3x+30 =180 add allof them

3x=180 -30

3x= 150

×=150/3

x= 50

now

x+3 =50+3= 53

x+20=50+20 =70

x+7 = 50 +7 =57

check :

53 +70= 123

123+57 =180

thats show its right 180 =180 lhs =rhs

Answer 2

Given :

• (x + 20)°
• (x + 3)°
• (x + 7)°

To find :

• the value of x

Solution :

⇒ Total internal Angles = 180°

= (x + 20)° + (x + 3)° + (x + 7)° = 180°

= x + 20° + x + 3° + x + 7° = 180°  

= 3x + 30° = 180°

= 3x = 180° - 30°

= 3x = 150

= x = 150/3

= x = 50

⇒ Now, let's find the angles.

x + 3° = 50 + 3 = 53°

x + 20° = 50 + 20° = 70°

x + 7° = 50 + 7° = 57°

• Therefore, the angles are 53°, 70°, and 57°.
