Answer:
200
Step-by-step explanation:
The perimeter of the triangle is: 4x+9
Step-by-step explanation:
Perimeter is the measurement of boundary of any closed figure.
Given
s1 = x+4
s2 = x+8
s3 = 2x-3
So, the perimeter will be the sum of all three sides
Hence,
The perimeter of the triangle is: 4x+9
Keywords: Perimeter, triangle

Step-by-step explanation:
Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.
52 = ½ (x − 38)
x = 142
Arc angles add up to 360.
360 = 80 + 38 + z + x
z = 100
Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.
y = x/2
y = 71
1) question 18 of 20
-7x/5-(4y)=7
4y=-7x/5-(7)
y=-7x/20-(7/4).
if x=0 ⇒y=-7*0/20-7/4=-7/4 ⇒y-intercept is-7/4
fi y=0 ⇒ -7x/20-(7/4)=0
-7x/20=7/4
x=(7*20) / [4*-(7)]=-5 ⇒x-intercept is -5
Solution: D) x-intercept is -5 ; y-intercept is -7/4
Question 19 of 20
P₁=(x₁,y₁)
P₂=(x₂,y₂)
m=slope
m=(y₂-y₁) / (x₂-x₁)
Then:
A(1,7)
B(10,1)
m=(1-7) / (10-1)=-6/9=-2/3.
Solution: B)-2/3
Question 20 of 20:
y-y₀=m.(x-x₀)
A(4,3)
B(-4,-2)
m=(-2-3) / (-4-4)=-5/-8=5/8
y-3=(5/8).(x-4)
y=5x/8-(20/8)+3
y=5x/8-(20/8)+24/8
y=5x/8+(4/8)
y=5x/8+1/2
solution: B) y=5x/8+1/2
