All triangles must equal 180°. So there you have a right angle which = 90° and a 25° angle. add those together to get 115°. Now do 180-115=65°. the missing angle is 65°.
Answer:
a = 70 km/h - 20 km/h / 0.008 h = 50 km/h / 0.008 h = 6250 km/h²
Perimeter = 2*(length +width)
perimeter = 2*(3x + (3x +(2x+6)))
.. = 2*(3x +3x +2x +6)
.. = 2*(8x +6)
perimeter = 16x +12
If x=3, the perimeter is 16*3 +12 = 60 inches.
Answer: y = 5y - (-2) < 17 =5y + 16
