Sin(60) = ¹/₂√3
cos(60) = ¹/₂
tan(60) = √3
The answer is D.
Answer:
26°
Step-by-step explanation:
AC=tan 64
BC=x=sec 64
Using sine rule
(Sin 64)/tan 64 = (sin BAC)/sec 64
Cos 64 = (sin BAC)(cos 64)
Sin BAC= 1
BAC=90
ACB+ 64+90=180
ACB= 26°
C. Supplementary
This means their angles add up to 180° which is a straight line
Answer:
$240
Explanation:
12 × 8 = 96 _________ area in square feet
96 × 2.50 = 240 _________ in dollars
50 divided by 8 = 6.25
1oz perfume = $6.25
110 divided by 17 = 6.4705
1oz perfume = $6.4705
Therefore the second option is cheaper
