Answer:

All you have to do is divide both sides by 2.5 to find your answer.

2.5x / 2.5 = 35 / 2.5

x = 14

The answer is X = 14.

I hope this helps!

Answer: 80

Step 1: Find $\frac{1}{2}$ of 168.

168 ÷ 2 = 84

Step 2: Subtract 4, since Brandon sold 4 more adult tickets.

84 - 4 = 80.

Answer:

Therefore 'x' is equal to 65.4°

Step-by-step explanation:

In Right Angle Triangle ABC

∠ B = 90°

AC = Hypotenuse = 12

CB = Adjacent Side = 5

To Find:

∠ C = x

Solution:

In Right Angle Triangle ABC Cosine Identity we have

$\cos C = \frac{\textrm{side adjacent to angle C}}{Hypotenuse}\\$

Substituting the values we get

$\cos C = \dfrac{CB}{AC}=\dfrac{5}{12}$

$\angle C = \cos^{-1}(0.4166)=65.37=65.4\°$

Therefore 'x' is equal to 65.4°
