Step-by-step explanation:
7x−3y+2=0
Add -7x to both sides.
7x−3y+2+−7x=0+−7x
−3y+2=−7x
Add -2 to both sides.
−3y+2+−2=−7x+−2
−3y=−7x−2
Divide both sides by -3.
−3y /−3 = −7x−2 /−3
which equals d)

Answer:
12.58 feet.
Step-by-step explanation:
Ron wants to build a 14 ft. ramp with an angle of the rise of 26° and the height of the ramp is about 6.1 ft.
We have to find out the length of the base of the ramp.
Now, the ramp forms a right triangle with the base and the height and here, the hypotenuse of the triangle is the ramp itself i.e. 14 ft.
If the base length is x feet, then we can write using the trigonometry
⇒ x = 14 cos 26° = 12.58 feet. (Answer)
