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

Consider this right triangle with given measures what is the unknown length

DIA [1.3K]

Answer:

b = 9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

b² + 12² = 15²

b² + 144 = 225 ( subtract 144 from both sides )

b² = 81 ( take the square root of both sides )

b = $\sqrt{81}$ = 9
