Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
Vertical Angles are the congruent angles opposite each other when two lines cross
see the attached figure to better understand the problem
m<ACD=m<BCE ------> by vertical angles
m<ACB=m<DCE ----> by vertical angles
Answer:
negative
Step-by-step explanation:
A negative value raised to an even exponent is positive
A negative value raised to an odd exponent is negative
= - 512 ← negative
= 256 ← positive
Answer:
an isosceles right triangle
Step-by-step explanation:
The square of the length of a side can be found from the distance formula:
d^2 = (x2-x1)^2 +(y2-y1)^2
The square of the length of WX is ...
WX^2 = (-3-(-10))^2 +(-1-4)^2 = 49+25 = 74
The square of the length of XY is ...
XY^2 = (-5-(-3))^2 +(11-(-1))^2 = 4 +144 = 148
The square of the length of YW is ...
YW^2 = (-10-(-5))^2 +(4 -11)^2 = 25 +49 = 74
The sum of the squares of the short sides is equal to the square of the long side, so this is a right triangle. The squares of the short sides are equal, so this is an isosceles right triangle.
