Answer: <ACB = 50 degrees
Step-by-step explanation: Since the interior angles of a triangle is always equal to 180 degrees, you would add both given degrees which is 40 and 90 (because of the right angle) and then subtract that answer (130) from 180
X-5=speed of car B
x = speed of car A
Distance = speed times time
distances is equal so
(x-5)(4.5)=(x)(4)
4.5x-22.5=4x
multiply both sides by 2 to get rid of the decimals
9x-45=8x
subtract 8x from both sides
x-45=0 a
add 45 to both sides and get
x=45
speed of car A = 45 mph
Speed of car B = 45-5 or 40 mph
Speed of car B = 40 mph
