I need help ASAP please ant thank you <br> what is x
Marizza181 [45]

Answer:

(3x-17)°+(x+40)°+(2x-5)°=180°[sum of angle of triangle]

6x°+18°=180°

6x°=180°-18°

x°=162°÷6°

x°=27°

Again,

=3x-17. 2x-5. x+40°

=3×27-17. =2×27-5. =27+40

=64°. =49°. =67°

Solve the following application problem. Be sure to show your system of equations and the steps to solve the problem.
ololo11 [35]

Answer:

  • boat: 6 mph
  • current: 2 mph

Step-by-step explanation:

The relationship between time, speed, and distance is ...

  speed = distance/time

For boat speed b and current speed c, the speed downstream is ...

  b +c = (16 mi)/(2 h) = 8 mi/h

The speed upstream is ...

  b -c = (16 mi)/(4 h) = 4 mi/h

Adding the two equations eliminates the c term:

  2b = 12 mi/h

  b = 6 mi/h . . . . . divide by 2

Solving the second equation for c, we get ...

  c = b -4 mi/h = 6 mi/h -4 mi/h = 2 mi/h

The speed of the boat in still water is 6 mi/h; the current is 2 mi/h.
