Step-by-step explanation:
Given,
Angle ADC = 118°
According to the question
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°.

Answer: Length = 9 units
Step-by-step explanation:
Let L represent the length of the rectangle.
The width of a rectangle is 2 units less than the length. It means that the width of the rectangle is (L - 2) units.
The formula for determining the area of a rectangle is expressed as
Area = length × width
The area of the rectangle is 63 units. It means that
L(L - 2) = 63
L² - 2L = 63
L² - 2L - 63 = 0
L² + 7L - 9L - 63 = 0
L(L + 7) - 9(L + 7) = 0
L - 9 = 0 or L + 7 = 0
L = 9 or L = - 7
Since the length cannot be negative, then
L = 9 units
Width = 9 - 2 = 7 units

Hope this answer will help you.
Have a great time
Simple...
you have: 6a+3b-8
a=4 and b=5
Plug in what you know-->>
6(4)+3(5)-8
24+15-8
39-8
31
Thus, your answer.
