Using Triangle sum theorem you add all the angles to make 180. So 47.7+51.1+<1=180
98.8+<1=180
-98.8 -98.8
<1= 81.2
Answer:
Domain: x=(0,∞)
Range: f(x)=(-∞,∞)
Step-by-step explanation:
For the domain:
The square root of a number is defined in real numbers only for positive numbers.
For the range:
The square root of a number could be positive or negative with any restriction. For example, 
could be 5 or -5.

The expression representing the perimeter is 6x + 39
x = 3. 8
<h3>What is the perimeter?</h3>
The formula for perimeter of a rectangle is given as;
Perimeter = 2 ( length + width)
From the image shown, we have that:
- length = 2x
- width = x + 13
Now, let's substitute the value
Perimeter = 2 ( 2x + x + 13)
collect like terms
Perimeter = 2 ( 3x + 13)
Expand the bracket
Perimeter = 6x + 39
If perimeter = 62
62 = 6x + 39
6x = 62 - 39
6x = 23
x = 23/ 6
x = 3. 8
Thus, the expression representing the perimeter is 6x + 39
