PLEASE HELP I NEED TO TURN THIS IN BEFORE 2. what fractions of the second ten counting numbers (11,12,13...,.18,19,20) Are composite and prime

will be the brainest

Iwill give ! if m∠a=59 and m∠3=81°, what is m∠b? m∠b= _[blank]_°

What is the solution to the equation below? 3/x-2+6=square root x-2 +8

1. 2. ∠b and ∠y are right angles. 3.? 4.? which two statements are missing in steps 3 and 4? ∠x ≅ ∠c △abc ~ △zyx by the sas similarity theorem. ∠b ≅ ∠y △abc ~ △zyx by the sas similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem.
