Answer:
The answer to your question is x = 3.356 cm
Step-by-step explanation:
This is a right triangle so we can use the Trigonometric functions to solve this problem.
Data
Ф = 40°
Adjacent side = 4 cm
Opposite side = x
Process
1.- We must know the lenght of the opposite side so we must use the tangent to solve it.
tangent Ф =
2.- Solve it for Opposite side
Opposite side = tanФ x Adjacent side
Opposite side = tan 40° x 4
Opposite side = 0.839 x 4
Opposite side = 3.356
Opposite side = x = 3.356 cm

Answer:
b) 15 winners
Step-by-step explanation
if 3 winners get $720,000 each that means there is $2,160,000 total. So if each winner gets $144,000 each that means there are 15 winners.
(2,160,000/ 144,000)
Answer:
x = 2
Step-by-step explanation:
3x + 12 = 18
3x - 12+12 = 18-12
3x = 6
3x/3 = 6/3
x = 2
Let justin's velocity is x and joan's is y
x = y +10
4x + 4y = 480 , x + y = 120 .......... (y+10) +y = 120 , 2y = 110 , y = 55 mph
x = 65 mph
