I believe your answer would be 14(6+3x) XD
Answer:
D
Step-by-step explanation:
or, x=88+46(exterior angle is equal to sum of two opposite interior angle)
or, x=134
B1 to H1, B3 to H2, B2 to H3.
The vehicle traveling 60 mph is going 4 times as fast. the brakes must do an amount of work that's equal to the original kinetic energy. the brakes exert the same amount of force no matter what the case is, so the stopping distance will be four times as long for the car going 60 mph compared to the car going 30 mph.
If all the angles are 60 degrees, this is an equilateral triangle. This means that all the sides have the same lengths. Whatever length side a is, b and c have the same length.
Hope this helps :)
