Anyone know the answers to 18,19, and 20?I need help I’m so tired

18. 2 times a number p squared

19. 3 times a number m to the power of 5

20. 1/2 plus 2

Step-by-step explanation:

R ≈ 17.7

S ≈ 19.0

Step-by-step explanation:

The angles of the triangle are 90, 43, and 47. Given these we can apply the law of sines.

26/sin(90) = s/sin(43), giving you 17.73195, rounding to 17.7.

26/sin90 = r/sin(47), giving you 19.01519, rounding to 19.0.
