Answer and Step-by-step explanation:

We are given an isosceles triangle, shown by the fact that there are two red marks on two sides, indicating that the sides are congruent in length, which means the base angles are congruent as well.

Add the angles together and equal it to 180.

34 + x + 81 + x + 81 = 180

Simplify.

115 + 2x = 180

Subtract 115 from both sides of the equation.

2x = 65

Divide both sides of the equation by 2.

x = 32.5 is the answer.

Given that v=234 3√p/w (cube root)
where 
p is the horsepower of the car and
w is the weight (in pounds) of the car
v is the velocity in miles per hour

p = 1311 hp
w = 2744 lb
substitute the given value to the equation to solve for the velocity

v = 234 3√(1311 / 2744)
v = 183 miles per hour is the velocity of a car at the end of a drag race.
