Answer:
3
Step-by-step explanation:
let unknown point (x, -2)
-2(x)+4=-2
-2x=-6
x=3
Answer:
b=17.75 ft
Step-by-step explanation:
We will answer this using Pythagorean Theorem.
Since the bottom of a ladder is 3 feet from the wall, and the ladder is 18 ft long, the ladder is the hypotenuse. Knowing pythagorean theorem (a^2+b^2=c^2), we can plug it in.
3^2 + b^2 = 18^2
9+b^2=324
b^2=315
b=17.75 ft
Answer:
Step-by-step explanation:
Exponent laws:
2pirad=360 deg
so
xrad/2pi=ydeg/360
times both sides by 360 to solve for ydeg
180xrad/pi=ydeg
so
7/9pi rad
180(7/9pi)/pi=ydeg
140=ydeg
140 deg
A is answer
