Question

In the picture provided, right triangle ABC is drawn with a 72 degree angle. For right triangles with it an angle of 72 degrees the ratio of the side opposite the 72 degree angle compared to the hypotenuse is 19/20. If the hypotenuse. AC has a length of 100 what is the length of the opposite side to 72° angleBC.​

Answer 1

B

Explanation:

Answer 2

105,3≈105

Explanation:

sin 72°=19/20

sin 72°=100/x

x=(20*100)/19=105,3

x=BC

x- is hypotenuse
