Answer:
10.2cm
Step-by-step explanation:
tan(60)=x/3
3tan(60)=x
5.2cm=x
2+3+5.2= 10.2cm
that is the perimeter
Answer:
Only one
Step-by-step explanation:
46=3x+7 /-7
39=3x /:3
13=x
I think D is the answer beacuse all A,B, and C are incorrect.
Answer:
y = -x +2
Step-by-step explanation:
First let's find the slope.
(-1,3) and (4,-2)
3 - -2/ -1 - 4 = 5/-5 = -1
Slope = -1
Now let's use slope intercept form:
y1-y2=m(x1-x2)
Let's plug in our slope for m.
y1-y2= -1 (x1-x2)
And now let's substitute y2 and x2 for one of our points, I'll use (4,-2)
y1+2 = -1(x1- 4)
y= -x + 4 -2
y = -x +2
