Answer:
4.8
Step-by-step explanation:
Multiply 5*4.8 equal 21.6
the sum of the angles in a triangle = 180°, thus
x +
x +
x = 180
multiply through by 6
6x + 3x + x = 1080
10x = 1080 ( divide both sides by 10 )
x = 108
the angles are 108°, 54° and 18°
Since all the angles are different and the largest is 108°
The triangle is an obtuse scalene triangle
(a) 1,1 (b) 3,2 (c) 3,2 (d) 1,5
Based on the characteristics of <em>linear</em> and <em>piecewise</em> functions, the <em>piecewise</em> function

<h3>How to determine a piecewise function</h3>
In this question we have a graph formed by two different <em>linear</em> functions. <em>Linear</em> functions are polynomials with grade 1 and which are described by the following formula:
y = m · x + b (1)
Where:
- x - Independent variable.
- y - Dependent variable.
- m - Slope
- b - Intercept
By direct observation and by applying (1) we have the following <em>piecewise</em> function:

15x + 28y = 116
x + y = 6
that would be ur system of equations
