Would really appreciate the help???

b=10.95,A=45° and B=45°

Step-by-step explanation:

Step-by-step explanation:

in a right angled triangle

c^2=a^2+b^2

b^2=c^2-a^2

b=√(c²-a²)

or b=√(13²-7²)

=√(169-49)

=√(120)

=2√(30)

by sin formula

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

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
