Answer:
The second ramp needs to have 25°.
Step-by-step explanation:
Required ramp angle for driving the car from the ground = 35°.
First ramp angle = 15°
Therefore, second ramp angle equals required ramp angle minus first ramp angle, which is = 35° - 15° = 20°
The 20° ramp angle will make the total ramp angle to be equal to 35°.
That is 15° + 20° = 35°
answer is y^2-6y+9
first take out the value of x from equation 1 which is x=(2-y)
then put the value of x in equation 2 u will get ur answer as y^2-6y+9
