The Answer to this problem is (the line y=x). I'm positive that this is the right answer!!!
Since we know a triangle only has 180 degrees we can say:
99+3x+x+5=180
Then we can solve for x:
4x+104=180
4x=76
x=19
Answer:
step two
Step-by-step explanation:
Answer:
Figure RST is congruent is R´S´T´
Step-by-step explanation:
Given that R´S´T is a reflection of RST, we know that is a rigid transformation, so it is congruent (the same size & shape).
Hypotenuse by Pythagoras theorem = 407.83.
