The value of x=9° and ∠B=40°
Step-by-step explanation:
From angles relationship, ∠A =∠B=corresponding angles
5x-5°=3x+13°
5x-3x=13°+5°
2x=18°
x=18/2 =9°
∠B=3x+13°= 3×9°+13° = 27° +13° =40°

This is the answer
Step-by-step
What you do is get into the form
(x-h)^2+(y-k)^2=r^2
(h,k) is center
r=radis
complete the square with x and y
x^2+y^2-2x+4y-11=0
group x and y terms together
(x^2-2x)+(y^2+4y)-11=0
take 1/2 of linear coefieicnt and add postive and negative
for x^2-2x, -2/2=-1, (-1)^2=1
for y^2+4y, 4/2=2, 2^2=4
(x^2-2x+1-1)+(y^2+4y+4-4)-11=0
complete the square
(x-1)^2-1+(y+2)^2-4-11=0
add like terms
(x-1)^2+(y+2)^2-16=0
add 16 both side
(x-1)^2+(y+2)^2=16
(x-(1))^2+(y-(-2))^2=4^2
(x-h)^2+(y-k)^2=r^2
(h,k)
(1,-2)
r=4
center is (1,-2)
radius is 4 units
Answer:
1) -2x-1 < 3
3) -3x+5 > 14
Step-by-step explanation:
You want x to equal the number that the point is on!
If you solve for #1 or #3 just remeber that when you divide or multiply on both sides of the inequality you must flip the sign!
