The problem asks which two triangles are congruent, or identical.
The correct answer is B) ΔDEF ≅ ΔJKL
Angle D corresponds to angle J, at 38°
Angle E corresponds to angle K, at 46°
Angle F corresponds to angle L, at 96°
Angles are congruent.
Side DE corresponds to side JK, at 8.8cm.
Side FE corresponds to side LK, at 5.4cm.
Sides are congruent.
Add 5 to both sides
y + 5 = x^2
Take the square root of both sides
±√y + 5 = x
Switch sides
<u>x = ±√y + 5</u>
Answer:
The average speed is 465 mph
Step-by-step explanation:
1860/4 = 465
50 times 28, you will get 1400.
If trying to mental calculate, I would :
28=20+8
50 times 20 = 1000
50 times 8 = 400
Then add them up to 1400.
