What is the length of SR?

9 units
12 units
15 units
18 units

Answered by maham237 @



we know that

In the right triangle RSQ

 cos\ S=\frac{RS}{SQ}

 cos\ S=\frac{RS}{25} ------> equation  1

In the right triangle RST

 cos\ S=\frac{ST}{RS}

 cos\ S=\frac{9}{RS} ------> equation  2

equate equation  1 and equation  2

 \frac{RS}{25}=\frac{9}{RS}\\ \\ RS^{2} =25*9\\ \\ RS=\sqrt{225} \\ \\ RS=15\ units

therefore

the answer is

the length of SR is  15\ units
