Length of x is 98.2 m
<u>Step-by-step explanation:</u>
Step 1:
Use the trigonometric ratio tan 27° to find the common side of both the right angled triangles.
tan 27° = opposite side/adjacent side = opposite side/9
∴ Opposite side = 9 tan 27° = 9 × - 3.27 = -29.46 m
Step 2:
Use this side and trigonometric ratio cosine to find the value of x.
cos 49° = adjacent side/x = -29.46/x
∴ x = -29.46/cos 49° = -29.46/0.30
= 98.2 m (negative value neglected)
<u>Answer</u>
3/4
<u>Explanation</u>
There are 17 subs that are to be shared between 22 children. To get that we divide 17 by 22.
∴ 17 ÷ 22 = 17/22
= 0.77272727...
From the choices we can get the closest fraction by converting them to decimals.
1/2 = 0.5
The difference from the correct answer = 0.77 - 0.5 = 0.27
3/4 = 0.75
The difference from the correct answer = 0.77 - 0.75 = 0.02
2/3 = 0.67
The difference from the correct answer is 0.77 - 0.67 = 0.1.
The closest amount is 3/4 since it has the least deviation of 0.02 from the correct amount.
I was stuck there too i have no idea how
The answer is B Complementary
