Alchen [17]

Answer: 26.24 inches

Step-to-step explanation:

Given:

The scale factor to model car= $\frac{1}{64}\ inches$

Thus, if diameter of tire of the actual car is k then diameter of model car = $\frac{1}{64}k$

Since, the diameter of tire of the model car= 0.41 inches

$\\\Rightarrow\frac{1}{64}k=0.41\\\Rightarrow\ k=0.41\times64\\\Rightarrow\ k=26.24\ inches$

hence, the diameter of tire of the actual car= 26.24 inches

Soryyyyyyyyyyyyyy this one to

alukav5142 [94]

The answer is B - 43.25

The two congruent sides will have congruent angles. One angle measurement is given. Triangle angles equal 180.

Take 180 and subtract the given angle 93.5. Then divide by 2 to get the measurements x and the other unknown.

180 - 93.5 = 86.5

86.5/2 = 43.25
