The triangles are similar. what is the value of x? enter your answer in the box. x = two right triangles. the larger right triangle is labeled x on the longer leg, 12 on the shorter leg and 20 on the hypotenuse. the smaller triangle is labeled 4 on the longer leg, 3 on the shorter leg, and 5 on the hypotenuse.

Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar. consider the given table.

Can someone me with these two circle theorem questions asap?
