Answer:
106
Step-by-step explanation:
Answer:
36cm^2
Step-by-step explanation:
Since the square was enlarged by a scale factor 2, sides of the old square = 12/2
= 6
Area of the original quare = L x L
= 6 x 6
= 36cm^2
Answer:
5.006
41.056
31.289
51.977
7.884
Step-by-step explanation:
1) sin x = opposite side / hypotenuse
sin 24.3° = 2.06 / hyp
hyp = 2.06 / sin 24.3 = 5.<u>0059</u>006616019108320511866543651
rounding to 3 significant figures
= 5.006
2)cos x = adjacent side / hypotenuse
cos 47 = 28 / x
x = 28 / cos 47 = 41.<u>0558</u>17197909497891901840157945
= 41.056
3) cos x = adjacent side / hypotenuse
cos 56.1 = x / 56.1
x = 56.1 * cos 56.1 = 31.<u>2895</u>00613760617368691451544764
= 31.289
4) tan x = opposite side / adjacent side
tan 68 = x / 21
x = 21 * tan 68 = 51.<u>9768</u>239217422123300402781676
= 51.977
5) sin x = opposite side / hypotenuse
sin 21 = x / 22
x = 22 * sin 21 = 7.<u>8840</u>948899966060166510313670963
= 7.884
Answer:
A
Step-by-step explanation:
← divide numerator/ denominator by 4
= 
Thus A form a proportion
≠ 
Thus B is not a proportion
← divide numerator/ denominator by 4
= 
≠
Thus C is not a proportion
≠
Thus D is not a proportion
