The three angles in a triangle are c. c.20 and c.40. Find c.

let's assume angle a as 20 degree , angle b as 40 degree

we know that angles in a triangle equals to 180°

a+b+c=180°

20°+40°+c=180°

c=180°-60°

c=120°

correct answer is infinitely many solutions

step-by-step explanation:

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

solving the above equation:

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

combining like terms

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

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
