Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° = , cos45° = , thus
sin60° = = = ( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp =
Now consider the right triangle on the right, using the cosine ratio
cos45° = = = ( cross- multiply )
x = × = → C
Answer:
it is correct or not ? if it is incorrect sorry
2/3x-1=1
+1 +1
2/3x=2
•3 •3
2x=6
/2 /2
x=3
0.8 is the greatest and 1/9 is the least
