Question

plzzz help me guys... i want to tally my answer​

Answer 1

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

[being it a straight line the sum will be 180]

3x+30=180

x+10=60 (dividing whole by 3)

›x= 60-10

›x= 50°

i hope it proved helpful...

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

$(x + 3) + (x + 20) + (x + 7) = 180(lie \: on \: the \: same \: line \: )$

$3x + 30 = 180 \\ \\ x = 180 - 30 \\ \\ 3x = 150$

x= 50°
