WY is one diagonal of the square WXYZ. Triangle WXY is a reflection of triangle WZY across WY Which of the following is a true statement about triangle WXY and triangle WZY?
A
The triangles are not congruent because only two pairs of corresponding sides are congruent,
B
The triangles are congruent because reflections preserve angle measures and side measures
С
The triangles are not congruent because it is impossible to know it W and Y are congruent
D
The triangles are congruent because the diagonalis congruent to the other two pairs of sides making all three pairs of sides congruent

answer: dead jah

step-by-step explanation:

bullet + jah= dead jah

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
