Find the scale of the known sides:
RT is similar to UW
5.4 /9 = 0.6
The smaller triangle is 0.6 times the larger one.
Multiply the length of RS to find UV:
6 x 0.6 = 3.6
The answer is A. 3.6 inches.
Answer:
Distribute -1/2 over (x - 4)
Divide both sides of the equation by -2
Complementary angles are those angles whose sum is 90 degree.
The measurement of two complementary angles are

There sum have to be 90 degree. That is

Combining like terms ,

Moving 20 to right side

Dividing both sides by 5

So the measurement of the angles are
