Which set of three angles could represent the interior angles of a triangle?
26 degrees, 51 degrees, 103 degrees
29 degrees, 54 degrees, 107 degrees
35 degrees, 35 degrees, 20 degrees
10 degrees, 90 degrees, 90 degrees

  26 degrees, 51 degrees, 103 degrees

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees. Look for the three measures that have that total.

__

  26 degrees, 51 degrees, 103 degrees

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
