Question

Help me in geometry please

Answer 1

In a rectangle, opposite sides are congruent.

So this means that
QT = RS
or
30 = 4x + 10
subtract the 10 from both sides

20 = 4x
divide both sides by 4

5 = x

answer is B. 5

Answer 2

QT = RS
30 = 4x + 10
20 = 4x
x = 5

answer
x = 5 It's B. second choice
