Step 1: Define

Identify variables

Angle θ = x

Opposite leg AC = 24

Adjacent leg CB = 35

Step 2: Solve for x

Substitute in variables [Tangent]: $\displaystyle tanx^\circ = \frac{24}{35}$
Inverse Trig [Tangent]: $\displaystyle x^\circ = tan^{-1}(\frac{24}{35})$
Evaluate: $\displaystyle x = 34.439^\circ$
Round: $\displaystyle x \approx 34^\circ$

Lemur [1.5K]

Answer:

6x + 25 ≤ 135

Step-by-step explanation:

Maximum amount to spend = $135

Boxes of popcorn = 2

Boxes of candy = 3

Cost per box of popcorn = $6

For 3 boxes = $6 * 3 = $18

Cost per box of candy = $3.50

For 2 boxes = $2 * 3.50 = $7

Item cost = Cost of candy and popcorn = $18 + $7 = $25

Ticket price = $6

Inequality to find number of friends ;

Let number of friends = x

Ticket cost = 6x

Hence ;

Ticket cost + item cost ≤ 135

6x + 25 ≤ 135
