Answer:
[ 60/25 ] x 5 km/h = 12 km/h
Step-by-step explanation:
If you plug in the x and y of choice b you would see that it does not equal 18.
6(3) + 3(-1) = 18
18 + (-3) = 15
the answer would be 3 I believe
Step-by-step explanation:
Angle A = 4x + 12 = 4(15) + 12 = 72°.
Acute is for angles that are less than 90°.
Obtuse is for angles that are between 90° and 180°, not inclusive.
Right is for angles that are 90°
Hence the answer is acute.
