Shalini found the sum of the measures of the interior angles of the triangle to be 175°. she knows the sum is supposed to be 180°. what was shalini’s error? m∠a = 45° m∠b = 85° m∠c = 45° shalini did not add the sum of the 3 angles correctly.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
