Answer:DC=7
Step-by-step explanation:
As it is written △ABC = △DBC. So the corresonding legs (the legs which are equal ) are as follows:
AC=DC AB=DB BC= BC
So DC=7 the same like AC
Answer:
9: -9
10: 18
11: 40
12: -4.5
1st number:-9
2nd number: -180
3rd number: -9
Step-by-step explanation:
I did it on paper but typed it on this stuff so you can understand it
PLEASE GIVE ME BRAINLIEST AND THANK YOU FOR THIS CHALLENGE VERY EASY TO DO.
Answer:
AB = 5cm
AC = 12cm
BC = 13cm
A = 90 deg
B= arctan(AC/AB)=arctan(12/5) =67.38 deg
C=arctan(AB/AC) =arctan(5/12) = 22.62 deg
Hello!!
So, the point slope equation is y-y₁=m(x-x₁)
In order to solve this with the points (-3,2) and (2,1), you need to find the slope.
The equation to find the slope is m=(y₂-y₁)/(x₂-x₁):
m=(2-1)/(-3-2)
m= -1/5
So your slope is-1/5
Now, using the point slope equation I stated earlier, ^^^ plug in either of the points you were given (Either -3,2 or 2,1) and your slope or m value (-1/5)
I'll show you both of the possible equations:
1) Using (-3,2)
y-(2)=m(x-(-3)) OR y-(2)=m(x+3)
Add 2 to both sides
y=mx+5
Answer is y=mx+5
2) Using (2,1)
y-(1)=m(x-(2))
Add 1 to both sides
y=mx-1
Answer is y=mx-1
Hope this helps!!!!
