Answer:
x=27
Step-by-step explanation:
3x+9 is a right angle because 3x+9 + a right angle make a straight line
3x+9 +90 = 180
Subtract 90 from each side
3x+9 = 90
We now can solve for x
3x+9-9 = 90-9
3x = 81
Divide each side by 3
3x/3 = 81/3
x=27
Answer:169pi
Step-by-step explanation:
Circumference(c)=26pi
Circumference(c)=2 x pi x radius(r)
26pi=2pi x r
Divide both sides by 2pi
26pi/2pi=(2pi x r)/2pi
13=r
Radius(r)=13
Area of circle=pi x r^2
area of circle=pi x 13^2
Area of circle=169pi
2/100 or 1/50 :p la respuesta
Answer:
yes it is parallel because the alternate interior angles are equal
