Answer:
x=40⁰
Step-by-step explanation:
==> (2x+40)⁰ + (x+20)⁰ =180⁰ (since it is a straight line so it'll form a straight angle)
==> 2x+40+x+20=180⁰
==>3x+60=180⁰
==> 3x=180-60
==>3x=120⁰
==> x= 120/3
==> x=40⁰
therefore, first angle
= 2x+40
=2×40+40
=80+40
=120
second angle
= x+20
=40+20
=60⁰
Verification:
first angle + second angle =180⁰
120⁰+60⁰=180⁰
180⁰=180⁰
LHS = RHS
PLEASE MARK ME THE BRAINLIEST!!
Answer:
We know that 2x + 40° + x +20° = 180° (linear pair)
3x + 60° = 180°
x = 120°/3
x= 40°
