PLEASE HELP ASAP IT'S DUE NOW I WAS UP ALL NIGHT TRYING BUT I CAN'T UNDERSTAND IT I'LL GIVE BRAINLIST TO THE FIRST CORRECT ANSWER​

Step-by-step explanation:

Angle 1 - (5a + 18)°

Angle 2 - (48 - a)°

Angle 3 - (8a - 30)°

Sum Of All Angles = 180° [Angle of Straight Line]

Therefore,

180 = (5a + 18) + (48 - a) + (8a - 30)

180 = 12a + 36

144 = 12 a

12 = a

Applying Value of a in Angles 1, 2 and 3,

Angle 1 - 5 (12) + 18 = 78°

Angle 2 - 48 - 12 = 36°

Angle 3 - 8 (12) - 30 = 66°

Therefore Biggest Angle is Angle 1 -78°

Hope I Helped,

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
