PLEASE HELP ME WITH MY TEST SO I CAN GRADUATE HIGHSCOOL

18

Step-by-step explanation:

by similarity, A corresponds to R, B to T, C to S

we know this bc all 3 angles are the same, so AAA similarity

looking at BC and TS, TS is 4/3 times the length of BC

BC is 3/4 times the length of TS

since the triangles are similar, this ratio applies to all lengths

so SR, which is the corresponding length to AC, is 24, so AC = 24 * 3/4 = 18

Part A: A) The number cannot be 7 as the 7 is a factor of 21.

Part B: As, 5 is only number which is have a cube more than 100 and less than 200.

The Answer is 5

Step-by-step explanation:

Part A Explanation↓

Given,

The number is a prime number.

The square of the number is more than 10 and less than 100.

The number is not factor of 21.

The number is 5.

5 is a prime number.

The square of 5 is between 10 and 100.

5 is not factor of 21.
