16 because 3 divided by 8 is 0.375 and 6 divided by 0.375 is 16.
Step-by-step 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
Answer:
-25
Step-by-step explanation:
7*3+x=-4
21+x=-4
x+21=-4
x+21-21=-4-21
