please help!

Answer 1

4

Explanation:

8 times square root of 2 = 11.31. 11.31 / 2 = 5.655. 5.655 divided by 1.414 = 4, so x = 4

Answer 2

Explanation:

Sin30=LJ/8square roof of 2

LJ=Sin30×8square roof of 2

so substitute LJ in the other triangle

Sin45=x/LJ

x=LJ×sin45

just replace LJ by Sin30×8square roof of 2
