Answer: A
<u>Step-by-step explanation:</u>
≅ 
⇒ ∠XOY ≅ ∠ZOY
≅ 
since they are both a radius
≅ based on reflexive property
∴ ΔXOY ≅ ΔZOY by SAS
So, 
≅ 
by CPCTC
ZY = 10.2 is given
so, XY = 10.2 by substitution property
Answer and explanation:
The wrong step <u>is changing the sign in step 2</u>
Such that; in step 1 the student had; (x + 6) and (x - 2)
In step 2, the student should have;
x + 6 = 0 and x - 2 = 0 instead of x - 6 = 0 and x + 2 = 0
Step 3, will thus be;
x = -6 and x = 2
Answer:
Step-by-step explanation:
= (12-8)/12 × 100%
= 4/12 × 100%
= 100/3%
= 33.33%
Answer: y - 19 = 2(x - 5)
Step-by-step explanation:
The point slope form is expressed as
y - y1 = m(x - x1)
Where
m represents slope
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The given points are (5,19) and (-5,-1)
y2 = - 1
y1 = 19
x2 = - 5
x1 = 5
Slope,m = (- 1 - 19)/(- 5 - 5) = - 20/- 10 = 2
To determine the equation, we would substitute x1 = 5, y1 = 19 and m= 2 into the point slope form equation. It becomes
y - 19 = 2(x - 5)
Hello,
Each side of a triangle is less than the sum of the 2 others sides;
x<8+12 ==>x<20
8<x+12 already realized
12<x+8==>x>4
So:
4<x<20 (i suppose that all the vertex are not on the same line)
