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!!

Leno4ka [110]

3:4 = G:B

1:5 = Mr. Smith's class: 7th Grade

2:7= 7th: Middle school

12 girls = 3 units

1 unit = 12/3= 4

Boys = 4x4= 16

<em>Whole class = 28 students</em>

Class : Grade = 1:5     <em> 7 = number of units in  Mr. Smith's class</em>

28 = 1 unit

5 units= 28x5= 140 <em>There are 140 kids in the grade</em>

140 = 2 units

1 unit = 140/2= 70

70x7=490

<u><em>There are 490 students in the whole grade</em></u>
