Step-by-step explanation:

Given,

Angle ADC = 118°

According to the question

11x - 7 + 5x - 3 = 118

=  > 11x   - 7 + 5x = 118 + 3

=  > 11x + 5x = 121 + 7

=  > 16x = 128

= x =  \frac{128}{16}

=  > x = 8

Now let's find the value of angle ADB

In the question it is mentioned that Angle ADB = (11x - 7)°

We know that x = 8 °

<h3 /><h3 /><h3>so let's get into this sum :)</h3>

Angle ADB = (11x - 7)°

= (11 × 8 - 7)°

= (88-7)°

= 81 °

So the answer is the first option i.e. 81°.

HOPE IT HELPS YOU!!

Price of each ride , p = $3 .

Number of rides , r = 3 .

To Find :

Total money spend if he goes on 5 rides and for r number of rides .
